Support query string in URI for Application Access

[ArunNadda]

What would you like Teleport to do?

As confirmed in 15796, URI string in application access does not support query string (like https://localhost/xslweb/login.do?useLegacy=1). This FR is to support query string in URI.

What problem does this solve?

Application can be configured to land on specific page based on query string.

If a workaround exists, please include it.

This can be achieved using a proxy path configuration to default to query string, but if multiple paths are required for same app, this will not work.

I've moved the c-xa tag to the original and will close this one out.
