Deprecate prometheus.listen_address and prometheus.enable

See merge request gitlab-org/gitlab!50500

We introduced `prometheus.server_address` setting in `gitlab.yml` which
is to be Rails application's SSOT regarding a Prometheus address.
Hence, we can deprecate the existing settings `enable` and
`listen_address`.

Changes:
* To `Gitlab::Prometheus::Internal` class methods:
  * `server_address` method renamed to `uri_without_protocol`, to
    reflect what the method actually does.
  * `listen_address` method renamed to `server_address`.
  * `promtheus_enabled?` method now depends on presence of
    `server_address`.

* To `Gitlab::DatabaseImporters::SelfMonitoring::Project::CreateService`
  class methods:
  * `prometheus_listen_address` method renamed to
    `prometheus_server_address`.
  * `internal_prometheus_listen_address_uri` renamed to
    `internal_prometheus_server_address_uri`.

Since we've always intended to have these various backup methods for
recovering data in our integration but we've never clearly documented
them we will write this down as a rough draft for now. If we are really
going to rely on this and encourage it's use we should also be testing
it and automating parts of it but that is more expensive and therefore
writing down what we know today is better than nothing.

These logs can be useful in the event of disaster recovery by replaying
the updates during a period of time from logging information. The
previous format was being blocked before ingestion into our logging
infrastructure likely due to the `wiki` field having an incorrect
format as field names cannot be re-used in our logs without them being
the same type. Either way this new format should not conflict and is
more machine readable than the previous one.

A list item wasn't indented as far as it should be, and an image
was over 2000px on the longest side. I ran the image through pngquant
afterward to compress the file size down as well.
