Remove dependency on infra in monitoring plugin (#203551)

Blocked by https://github.com/elastic/kibana/pull/203492

The monitoring plugin is currently marked as observability plugin
because it's relying on the `infra` plugin.

However, in practice, no functionality is actually used. This PR removes
the dependency -it makes monitoring and logstash a `platform/private`
plugin as well (logstash needs to go along with monitoring, but that
should be fine because it's only required by monitoring).

Some considerations left as comments in the code.
