IMPALA-10454L: Bump --ssl_minimum_version to tls1.2

TLS versions < 1.2 are now considered insecure. This patch improves
Impala's default security.

This is made possible now in part because Impala 4.0 dropped support
for Python versions < 2.7.9 (or 2.7.5 on certain distributions where
it has been patched) as lower Python versions do not support tls1.2

Testing:
- Existing SSL tests are updated to reflect the new default.
