MEDIUM: ssl: Add "show ssl crl-file" CLI command

This patch adds the "show ssl crl-file [<crlfile>]" CLI command. This
command can be used to display the list of all the known CRL files when
no specific file name is specified, or to display the details of a
specific CRL file when a name is given.
The details displayed for a specific CRL file are inspired by the ones
shown by a "openssl crl -text -noout -in <filename>".
