picodb(mssql): support all MSSQL pdo drivers 

For MSSQL make all connection attributes optional.
Handle differing DB connection params based on driver used.
connection can be made via ODBC DSN or server/hostname
username/password can be embedded in DSN definition or simply
omitted and single-signon will be attempted.
