Fix ssl db query params

[bmo-at-a9s]

Description

The fallback parsing of cf services was neglecting the fact that the database URI might contain query parameters.
This PR introduces changes to accomodate them, parse them out correctly and add them to the configuration struct.

Motivation and Context

How Has This Been Tested?

Unit tests have been added to cover this functionality. Additionally, a staging deployment including a database uri with query params was used to verify that the change works.
