IMPALA-10234: Add support for cookie authentication to impala-shell

IMPALA-8584 added support for cookie authentication to Impala.
This change adds cookie authentication support to impala-shell
as well when using 'hs2-http' protocol.

Testing:
- Unit tests were added to test cookie handling methods.
- Tested e2e manually with nginx HTTP proxy.
TODO:
- Test with Knox HTTP proxy as well.

> When IMPALA-8538 goes in, we'll have support for LDAP authentication over 
> http. The initial design will pass the credentials to LDAP for authentication 
> on every rpc. This has the potential to create a significant load on the LDAP 
> server. We can avoid hitting LDAP on every request by adding support for 
> cookie auth.
