tenant: add support to Log endpoints to status server

[dhartunian]

Previously, the tenant status server did not support the log-file related
endpoints leading to missing logs in the debug.zip when generating for a tenant
server.

This commit migrates the implementations from the standard status server into
the tenant, adjusts for fanout to instances instead of nodes, and leaves the
rest as-is.

Resolves: #91992
Epic: CC-5168

Release note (ops change): generating a debug.zip for a tenant server will now
include logs in the zip file.

The tenant and non-tenant status servers will be merged for 23.1, but this PR is intended for backporting so we can support logs in debug.zip for 22.2

[knz]

we're in agreement this will eventually become a single implementation shared with status.go, right?

no objection

- you are a hero with this turnaround time!

I went ahead and tested on a cluster where multiple SQL instances were running for a single tenant. Logs were collected from all instances 🎉

Encountered an error creating backports. Some common things that can go wrong:

1. The backport branch might have already existed.
2. There was a merge conflict.
3. The backport branch contained merge commits.

You might need to create your backport manually using the backport tool.
