IMPALA-6861: Fix OpenSSL initialization
Impalads currently initialize OpenSSL twice: once when initializing
Thrift and once when initializing KRPC. The initialization is
theoretically idempotent but not thread-safe, so its better to clean
this up.
This patch disables the Thrift version as its older (last updated in
2015) and the KRPC version contains logic specific to more recent
versions of OpenSSL. The catalogd and statestored also now use the
KRPC version instead of the Thrift version.
It also improves debuggability by adding some additional startup
logging.
Testing:
- Passed existing SSL tests.
