IMPALA-10206: Avoid MD5 Digest Authorization in FIPS approved mode

To compliant with FIPS requirement, we should use OpenSSL libraries
for cryptographic hash functions, instead of own hash functions.
This patch replace MD5 and SHA1 functions in Squeasel Web server
with OpenSSL APIs. It also force to turn off Digest Authorization
for Web server in FIPS approved mode since Digest Authorization
use MD5 hash and it doesn't comply with FIPS 140-2.

Testing:
 - Passed webserver-test.
 - Passed exhaustive tests.
 - Manually verified HTTP Digest Authorization could not be enabled
   by setting webserver_password_file on a FIPS enabled cluster.
