Implement basic CI metric reporting

[spalger]

This PR implements some API calls and Jenkins pipeline changes that attempt to do two things:

• store some information about builds as they are running in an external service
• store the amount of time the @kbn/optimizer runs triggered by our two distributable builds take, in the same service, using the CiStatsReporter.

This infrastructure will be expanded to collect additional metrics, and eventually will be used to report to PR authors how they are impacting key metrics with their PR.

Included some basic docs: https://github.com/spalger/kibana/blob/implement/ci-stats-build-creation/packages/kbn-dev-utils/src/ci_stats_reporter/README.md

Small thing, should this be !this.isEnabled()?

[spalger]

We could use that, but it wouldn't teach TypeScript that this.config should be considered non-null below.
