Update Redis.conf to improve TLS usability

Removing the default guidance in Redis.conf since this is not an available value.

fix for flaky psync2 test

*** [err]: PSYNC2: total sum of full synchronizations is exactly 4 in tests/integration/psync2.tcl
Expected 5 == 4 (context: type eval line 6 cmd {assert {$sum == 4}} proc ::test)

issue was that sometime the test got an unexpected full sync since it
tried to switch to the replica before it was in sync with it's master.

When using TLS with a Redis.conf file the line for TLS reading tls-cert-file redis.crt tls-key-file redis.key is interpreted as one complete directive. I am separating this on two separate lines to improve usability so users do not get the below error.

This makes simpler to give people help when posting such kind of errors
in the mailing list or other help forums, because sometimes the
directive looks well spelled, but the version of Redis they are using is
not able to support it.

Modules: Do not auto-unblock clients if not blocked on keys

fix github actions failing latency test for active defrag - part 2

it seems that running two clients at a time is ok too, resuces action
time from 20 minutes to 10. we'll use this for now, and if one day it
won't be enough we'll have to run just the sensitive tests one by one
separately from the others.

this commit also fixes an issue with the defrag test that appears to be
very rare.
