Add timeout for remoted socket to be ready in test_request_agent_info.py

[mdengra]

Related issue
Closes: #1579

Description

This PR modifies the test_request_agent_info.py of remoted tests to add a timeout for remoted socket to be ready. This timeout is only added in a specific use case, which is where the errors occur.

The number of use cases has also been reduced from nine to three, as those eliminated were redundant.

Finally, the documentation has been updated to include the above changes.

Configuration options

All the tests are run with the default configuration and the following options in local_internal_options.conf

remoted.debug=2
wazuh_database.interval=1
wazuh_db.commit_time=2
wazuh_db.commit_time_max=3
monitord.rotate_log=0

Tests

The comments will have the description for every test run

• Proven that tests pass when they have to pass.

I think that we should keep all the possible combinations of protocols that we have now since Wazuh 4.2. Before this version, the manager only accepted connections using only one protocol, but now it accepts both, TCP and UDP simultaneously.
This is just a suggestion so we can discuss this in our daily meeting to make a general decision for all the tests that have single protocols and a combination of them.

Could @mdengra execute this again, please? I would like to see if you have the same error. In case that you can't reproduce the fail, tell me and I will put my approval.

Hello @damarisg, I have rerun the tests but I have not been able to reproduce the error in my test environment.
