[feature]: Implement filters for testcase capture

[slayerjain]

Is your feature request related to a problem? Please describe.
We need the ability to filter test case capture by various fields such as URL, headers, etc.

Describe the solution you'd like
Provide a way to set filters in the SDK.

Describe alternatives you've considered
Provide filters from UI instead. This could be something we do later due to the potential complexities involved.

Additional context
We decided to add this urgently because we needed this to test keploy itself. We are interested in unit testing the keploy API which runs on /url/* space.
