Add F5 Cloud Exporter (1/3)

[gramidt]

Description:
Allow exporting of metric, trace, and log data to F5 Cloud

Link to tracking Issue:
#1964

Testing:
Unit tests are included

Documentation:
The documentation includes a short description and the configuration.

Notes:

• This exporter is currently just a wrapper around the opentelemetry-collector/otlphttp exporter, but includes F5 Cloud specific authentication. (Similar to how the awsprometheusremotewriteexporter is implemented)
• While this exporter is initially just an authentication wrapper for the otlphttp exporter, additional F5 Cloud specific metadata will be added in the near future.
• This is the first of 3 PRs. The second will include updates to the code owners and dependabot, and the third will add it to the binary. I'm happy to break this PR up too, but figured since it's just currently a wrapper around the OTLP exporter with some custom authentication logic, it would be pretty easy to review as is.

@anuraaga - We may need to start looking into and resolve the linting issue with the spanmetricsprocessor .

processor.go:58:123: newProcessor - result 1 (error) is always nil (unparam)
func newProcessor(logger *zap.Logger, config configmodels.Exporter, nextConsumer consumer.TracesConsumer) (*processorImp, error) {

[gramidt]

@anuraaga - Appears that the linting issue with spanmetricsprocessor has been addressed with the latest commits to master.
