Option to pass-in Password and SSL/TLS configuration for SINGLE and SENTINEL modes only

[dinbtechit]

Change Log

• Updated JDK compiler version to 1.8
• Adding additional parameters to pass-in password, SSL/TLS configuration for SINGLE and SENTINEL modes only.
• Updated the logic to split the Configuration String by comma outside square brackets only. For example: host=www.example.com,password=Pa$$word=,ssl=true,tls=[TLSv1, TLSv1.1, TLSv1.2] will be split to

  host=www.example.com,
  password=Pa$$word=,
  ssl=true,
  tls=[TLSv1, TLSv1.1, TLSv1.2]

• Updates to Usage and Build documentation. (Note - Usage Redis configuration to pass-in host, expiration, etc., via session-agent.java etc was not working.)
• Updating JUnit Test case.
• Adding a new configuration to create redis-single docker instance with password to test passwords.

TODO

• Add password ability to Redis Cluster mode.
