[Enhancement] Allows HttpMock to ignore query params from url path if given the option

[muhammadnawzad]

Recently, I encountered an issue where date-time values within query parameters were not accurately detected and parsed, leading to inaccuracies in the mocks I had. I had to either change the business logic to not use date-time values in query parameters, or to change the way the date-time values were parsed. For me, the former was not an option, so I had to change the way the date-time values were parsed.

Currently ActiveResource::HttpMock does not provide a way to omit the query parameters from the URL when matching a request, while I understand that this is probably not a common use case since it will lead to a lot of issues when the mocked URL is not specific enough, I still think it would be useful to have the option to omit the query parameters from the URL when matching a request.

In this PR I have added a options parameter, which defaults to {}. When the options[:omit_query_params] is set to true, the query parameters will be omitted from the URL when matching a request. This does not change the default behavior of the ActiveResource::HttpMock class, rather it adds an option to change the behavior. In addition, I have also added a method remove_query_params_from_path to remove the query parameters.

I hope this is not too much of a niche use case, and that this PR can be merged. If not, I would love to hear your feedback on this.
