Configurable token hash algorithm
Tokens were always hashed with md5. This change allows tokens to
be hashed with sha256 (or any other algorithm supported by the
keystoneclient token hash function). This is for security
hardening.
There's a new configuration option 'hash_algorithm' in the [token]
section. If this is not set then the server's behavior is the
same as before. If it's set to a hash algorithm (such as 'sha256'),
then PKI tokens will be hashed using that algorithm. Also, the
configured hash algorithm is set on the revocation list.
