Unlike PLAIN, XOAUTH2 and OAUTHBEARER, CRAM-MD5 authentication is not
supported by libcurl and requires OpenSSL. If the user tries to use
CRAM-MD5 authentication without OpenSSL, the previous behaviour was to
attempt to authenticate and fail with a die(error). Handle this in a
better way by first checking if OpenSSL is available and then attempting
to authenticate. If OpenSSL is not available, print an error message and
exit gracefully.
