+ Export metrics to Google Cloud Pub/Sub Service

+setup:
+ prerequisites:
+ list:
+ - title: ''
+ description: |
+ - First [install](https://github.com/googleapis/google-cloud-cpp/) install Google Cloud Platform C++ Client Libraries
+ - Pub/Sub support is also dependent on the dependencies of those libraries, like `protobuf`, `protoc`, and `grpc`
+ - Next, Netdata should be re-installed from the source. The installer will detect that the required libraries are now available.
+ configuration:
+ file:
+ name: 'exporting.conf'
+ options:
+ description: |
+ The following options can be defined for this exporter.
+ folding:
+ title: 'Config options'
+ enabled: true
+ list:
+ - name: 'enabled'
+ default_value: 'no'
+ description: 'Enables or disables an exporting connector instance (yes|no).'
+ required: true
+ - name: 'destination'
+ default_value: 'pubsub.googleapis.com'
+ description: 'Accepts a space separated list of hostnames, IPs (IPv4 and IPv6) and ports to connect to. Netdata will use the first available to send the metrics.'
+ required: true
+ detailed_description: |
+ The format of each item in this list, is: [PROTOCOL:]IP[:PORT].
+ - PROTOCOL can be udp or tcp. tcp is the default and only supported by the current exporting engine.
+ - IP can be XX.XX.XX.XX (IPv4), or [XX:XX...XX:XX] (IPv6). For IPv6 you can to enclose the IP in [] to separate it from the port.
+ - PORT can be a number of a service name. If omitted, the default port for the exporting connector will be used.
+
+ Example IPv4:
+ ```yaml
+ destination = pubsub.googleapis.com
+ ```
+ When multiple servers are defined, Netdata will try the next one when the previous one fails.
+ - name: 'username'
+ default_value: 'my_username'
+ description: 'Username for HTTP authentication'
+ required: false
+ - name: 'password'
+ default_value: 'my_password'
+ description: 'Password for HTTP authentication'
+ required: false
+ - name: 'data source'
+ default_value: ''
+ description: 'Selects the kind of data that will be sent to the external database. (as collected|average|sum)'
+ required: false
+ - name: 'hostname'
+ default_value: '[global].hostname'
+ description: 'The hostname to be used for sending data to the external database server.'
+ required: false
+ - name: 'prefix'
+ default_value: 'Netdata'
+ description: 'The prefix to add to all metrics.'
+ required: false
+ - name: 'update every'
+ default_value: '10'
+ description: |
+ Frequency of sending sending data to the external database, in seconds.
+ required: false
+ detailed_description: |
+ Netdata will add some randomness to this number, to prevent stressing the external server when many Netdata servers
+ send data to the same database. This randomness does not affect the quality of the data, only the time they are sent.
+ - name: 'buffer on failures'
+ default_value: '10'
+ description: |
+ The number of iterations (`update every` seconds) to buffer data, when the external database server is not available.
+ required: false
+ detailed_description: |
+ If the server fails to receive the data after that many failures, data loss on the connector instance is expected (Netdata will also log it).
+ - name: 'timeout ms'
+ default_value: '2 * update_every * 1000'
+ description: 'The timeout in milliseconds to wait for the external database server to process the data.'
+ required: false
+ - name: 'send hosts matching'
+ default_value: 'localhost *'
+ description: |
+ Hosts filter. Determines which hosts will be sent to the external database. The syntax is [simple patterns](https://github.com/netdata/netdata/tree/master/src/libnetdata/simple_pattern#simple-patterns).
+ required: false
+ detailed_description: |
+ Includes one or more space separated patterns, using * as wildcard (any number of times within each pattern).
+ The patterns are checked against the hostname (the localhost is always checked as localhost), allowing us to
+ filter which hosts will be sent to the external database when this Netdata is a central Netdata aggregating multiple hosts.
+
+ A pattern starting with `!` gives a negative match. So to match all hosts named `*db*` except hosts containing `*child*`,
+ use `!*child* *db*` (so, the order is important: the first pattern matching the hostname will be used - positive or negative).
+ - name: 'send charts matching'
+ default_value: '*'
+ description: |
+ One or more space separated patterns (use * as wildcard) checked against both chart id and chart name.
+ required: false
+ detailed_description: |
+ A pattern starting with ! gives a negative match. So to match all charts named apps.* except charts ending in *reads,
+ use !*reads apps.* (so, the order is important: the first pattern matching the chart id or the chart name will be used,
+ positive or negative). There is also a URL parameter filter that can be used while querying allmetrics. The URL parameter
+ has a higher priority than the configuration option.
+ - name: 'send names instead of ids'
+ default_value: ''
+ description: 'Controls the metric names Netdata should send to the external database (yes|no).'
+ required: false
+ detailed_description: |
+ Netdata supports names and IDs for charts and dimensions. Usually IDs are unique identifiers as read by the system and names
+ are human friendly labels (also unique). Most charts and metrics have the same ID and name, but in several cases they are
+ different : disks with device-mapper, interrupts, QoS classes, statsd synthetic charts, etc.
+ - name: 'send configured labels'
+ default_value: ''
+ description: 'Controls if host labels defined in the `[host labels]` section in `netdata.conf` should be sent to the external database (yes|no).'
+ required: false
+ - name: 'send automatic labels'
+ default_value: ''
+ description: 'Controls if automatically created labels, like `_os_name` or `_architecture` should be sent to the external database (yes|no).'

+ - Set the destination option to a Pub/Sub service endpoint. pubsub.googleapis.com is the default one.
+ - Create the credentials JSON file by following Google Cloud's authentication guide.
+ - The user running the Agent (typically netdata) needs read access to google_cloud_credentials.json, which you can set
+ `chmod 400 google_cloud_credentials.json; chown netdata google_cloud_credentials.json`
+ - Set the credentials file option to the full path of the file.
