Add deprecation warning of InfluxDB in docs
Problem to solve
We plan to deprecate InfluxDB in the next major version 13.0, therefore we would need to refer this on our documentation prior to that
Further details
Since we've instrumented GitLab with Prometheus as a standard. As we've gotten to parity on that instrumentation AND the available dashboards we will be removing InfluxDB support in favor of Prometheus in 13.0 version, we should document this in 12.6
Proposal
Add a section on our documentation specifying that we plan to remove support for InfluxDB
