This PR introduces a test case for TLS with `ca_dir`. First, we
did not have any tests for this case. Second, using `ca_dir` requires
to call `c_rehash` on the directory before it is loaded by DF. We
did not have this use case anywhere and therefore we thought there was
a bug when we used `ca_dir` only to find out that we need to call
`c_rehash` on the directory before we load the certificates. Now,
both a test and a use case are properly documented
* add missing test for ca_dir
* use rehash to properly show how to load ca directories instead of
files
Regression test sometimes fails because for a short period of time after `wait_available_async()` returns, the result of `ROLE` could still be different from `stable_sync`
[Failure example](https://github.com/dragonflydb/dragonfly/actions/runs/6726461923/job/18282759612#step:6:1863)
We change our state from `LOADING` to `ACTIVE` [here](d08d7f13b4/src/server/replica.cc (L426)), but then we change the sync state 2 times:
1. `!R_SYNCING` [here](d08d7f13b4/src/server/replica.cc (L427C28-L427C37))
2. And only later to `R_SYNC_OK` (meaning `stable_sync`) [here](d08d7f13b4/src/server/replica.cc (L221))
This is easy to reproduce by adding a sleep right after the set of state to `ACTIVE`, either before or after the flipping of `R_SYNCING` (with different returned states).
BTW without that added sleep I was not able to reproduce, having tried 1000s of times in various configurations.
We could change the order of things such that we first change `state_mask_` and only then switch state from `LOADING` to `ACTIVE` (which is probably the right thing to do), but that would require a subtle refactor, as we change these in a couple of places.
But we should keep in mind that this has no effect on users. So a simple sleep on the test side should fix this fairly well.
* chore: help users to fix a common mistake of setting quotes in the flagfile
Specifically, the confusion is often around the cron expression.

* add a python script to print the most recent log
* if CI timeouts, print the most recent log
* replace global timeout with timeout command
* upload all logs on failure()
* print uid + port + the log files for each df instance
* requirepass also updates ACL default user password
* update config set requirepass to include the new behaviour
* add tests
* fix non existent default user when loading empty files
* Update Http auth with username default instead of user
* skip auth for /metrics page
* add/improve tests
* fix a bug with admin port requiring auth on http even if nopass was set
* update helio ref
* update listener class to contain its respective Role
* fix http init to only include admin and main listener
* The issue was similar with test `network_disconnect_small_buffers` but this time the debug build could be slow enough for the replication to not finish. As a consequence, by the time the test reached the assertion, the log did not contain the expected output.
* chore(regression): test bptree on regression pytests
1. stop passing the flag use_zset_tree as it is true on default
2. fix ci test to run replication tests
3. change replication tests seeder to sometimes add more than 128 values
to zset to test the pbtree impl
