Add TLS & ACL options to healthcheck's redis configuration

[magederek]

What is the feature you want to add?
TLS & ACL configuration of healthcheck redis

Why do you want to add this feature?
In some scenario, e.g. when using the Amazon MemoryDB for Redis, we want to enable the TLS and ACL feature for authorization. However, till v1.8.0, the configuration of Redis only containes address, password and some other timeout options, which does not satisfy our demands.

current redis options of polaris healthcheck in polaris-server.yaml:

    healthcheck:
      checkers:
      - name: heartbeatRedis
        option:
          kvAddr: ##REDIS_ADDR##
          kvPasswd: ##REDIS_PWD##
          maxIdle: 200
          idleTimeout: 120s
          connectTimeout: 200ms
          msgTimeout: 200ms
          concurrency: 200

How to implement this feature?
Add TLS & ACL options to healthcheck's redis configuration, make it available to set tls and acl options via polaris-server.yaml

Additional context
TLS: redis-cli --tls
ACL: redis-cli --user USER -a PASS
