Test support for the new map, null and push message types. Map objects are parsed as a list of lists of key value pairs.
for instance: user => john password => 123
will be parsed to the following TCL list:
{{user john} {password 123}}
Also added the following tests:
Redirection still works with RESP3
Able to use a RESP3 client as a redirection client
No duplicate invalidation messages when turning BCAST mode on after normal tracking
Server is able to evacuate enough keys when num of keys surpasses limit by more than defined initial effort
Different clients using different protocols can track the same key
OPTOUT tests
OPTIN tests
Clients can redirect to the same connection
tracking-redir-broken test
HELLO 3 checks
Invalidation messages still work when using RESP3, with and without redirection
Switching to RESP3 doesn't disturb previous tracked keys
Tracking info is correct
Flushall and flushdb produce invalidation messages
These tests achieve 100% line coverage for tracking.c using lcov.
* Introduce a connection abstraction layer for all socket operations and
integrate it across the code base.
* Provide an optional TLS connections implementation based on OpenSSL.
* Pull a newer version of hiredis with TLS support.
* Tests, redis-cli updates for TLS support.
