feat: Support to pull Redis credentials from secrets in the CR

[velotioaastha]

Added support to pull REDIS entire configuration from secrets from Secrets when deploying CRD from yaml file.
Secret should look like this :

kind: Secret
metadata:
  name: my-redis-secret
type: Opaque
data:
  REDIS_PASSWORD: bXlwYXNzd29yZA==   
  REDIS_CA_CERT: bXljYQ== 
  REDIS_PORT: NjM3OQ==
  REDIS_HOST: bXlyaWRpcy5leGFtcGxlLmNvbQ==

I have some other thoughts, but I need to get some additional context from @jsbroks as to why we provide the redis creds as both a single connection string and multiple fields, and more imporant, what does the application actually use.

@velotioaastha The only way I could figure out how I wanted this implemented was to implement it myself. See #229
