networks needs to be list so they can be encoded in a json string
resetting con on the hosts where agent isn't reporting (possibly offline hosts)

Creates an http endpoint in mgr/cephadm to receive
http requests and an agent that can be deployed on
each host that will gather metadata on the host and
send it to the mgr/cephadm http endpoint. Should save the
cephadm mgr module a lot of time it would have to spend
repeatedly ssh-ing into each host to gather the metadata
and help performance on larger clusters.

They are part of our backtrace handling and typically developers
are not interested in them. Let's be consistent with the classical
OSD and hide them.

If the systemd target doesn't exist we need to just bypass enabling
it and return success or the host will just be stuck in maitnenance
mode.

Instead of fetching `pg_stats` from the python
part of manager module, we filter out the pgs
that are in active + clean state in ActivePyModules.cc
then parse these pgs along with `reported_epoch` and
the `total_num_pgs` of the clusters to global recovery
module.

This unit test checks that the "replacer" method in telemetry.component.ts works as it should. The replacer method takes the telemetry report and changes the ranges and values of the 'osd_perf_histograms' field from arrays to strings, thereby making the report more readable in the Dashboard Telemetry Preview.
This unit test needs improvement since it currently uses a test report rather than the real one.

`seastar::engine()` is available only for Seastar's threads;
it shouldn't be called outside of a reactor thread.
Unfortunately, this assumption is violated in `AlienStore`
where `OnCommit::finish()`, executed from a finisher thread
of `BlueStore`, calls `alien()` on `seastar::engine()`.
The net effect are crashes like the following one:
```
