check_dbi: Added SERVER_VERSION metric.

Browse source 
This metric compares the database engine server version with the specified
ranges. The version string [[[[A.]B.]C.]D.]E[.] is returned as E + D*100 +
C*10000 + B*1000000 + A*100000000 (see libdbi's dbi_conn_get_engine_version()
documentation).
