PyDAL for Azure MySQL

[rogeriosantosluz]

Hi I'd like to suugest two things to make PyDAL work with MySQL Azure:

1. Adjust REGEX_URI on MySQL class to accept user with "@", required for Azure MySQL connections
   "^(?P<user>[^:]+)(:(?P<password>[^@]*))?" will work
2. Make uriargs accept an extra argument called ssl_ca that will point to DigiCertGlobalRootG2.crt
   self.driver_args["ssl"] = {"ssl-ca": ssl_ca}
   mysql.txt

Thank you

Wow. I ignored this for one year and I feel bad. I would be happy to support this. Any chance you could make a PR and help test it.
