Update ACL tests and modify JedisPool tests (#2325)

- Test ACL with non-default user for standalone Redis instance (Jedis, Jedis with SSL, JedisPool)
- Removed Jedis with ACL tests where ACL feature was not being used and will not bring anything new even if used
- Removed JedisPool with ACL tests where ACL feature was not being used and will not bring anything new even if used
- Modify JedisPool (with/without ACL) tests
- Used try-with-resources in JedisPool (with/without ACL) tests
- Added a test related to issue #2318 and PR #2319 
- Added two minimal JedisPool constructor with user and password params (also testing those)
