MSSQL Connector faithfully propagates connection parameters from client to target service

[izgeri]

The PG and MySQL connectors transparently pass on any parameters passed on by the client in the connection request, and the MSSQL connector needs to be updated to do the same.

Note: credentials, host/port and SSL configuration information are not passed on to the server - they are set by Secretless config.

In this card, you need to read info from the client connection and translate it to the dsn (the data structure that go-mssql uses for connection config)

AC:

• MSSQL connector passes on any non-credential parameters submitted by the client in the connection request
• Unit tests exist to ensure the MSSQL connector transparently passes non-credential params
