DTT1 - Testing - Allow single Wazuh manager test

[rauldpm]

Description

We need to allow the DTT1 Testing module to use only a single Wazuh manager instead of a cluster, as a Wazuh manager itself can work

That means: The test should install, configure, and check all the current tests but it will not check the connection test to agents or other managers (workers) unless they exist

Origin: #5191

After talking with @davidjiglesias, @rauldpm , @pro-akim and @mhamra it was noted that it is necessary to modify the way in which the Wazuh manager is being installed to incorporate the central components with AIO. That said, this issue misses the point and is closed in pursuit of this issue #5219
