fix(5432): add query parameters in tracing url

[hi-ogawa]

What do these changes do?

Fixes #5432

As demonstrated in the issue, when query parameters are passed via params keyword argument, some of tracing callback doesn't provide URL with those parameters. Note that it's been working correctly if query parameters are passed in an "inline" fashion as in session.get("/?x=0") instead of session.get("/", params=dict(x=0)).

Currently, as far as I can tell, out of 7 tracing callbacks which give URL information:

on_request_start
on_request_redirect
on_request_end
on_request_exception
on_request_chunk_sent
on_response_chunk_received
on_request_headers_sent

these 4 tracing types don't include query parameters when passed via params.

on_request_start
on_request_redirect
on_request_end
on_request_exception

In this PR, I addressed this issue and added tests to demonstrate all 7 cases working as expected.
If there's something I'm missing, please let me know.
Thanks for the review!

Are there changes in behavior for the user?

Yes, as explained above.

Testing on python 3.7 is failing because I'm relying on some mock.Mock feature available only from python 3.8.
I'll work on a fix.

Backport to 3.8: 💔 cherry-picking failed — conflicts found

❌ Failed to cleanly apply 3e879ec on top of patchback/backports/3.8/3e879ec97923e9d29a4a277f942893ae7ed5f090/pr-6178

Backporting merged PR #6178 into master

1. Ensure you have a local repo clone of your fork. Unless you cloned it
   from the upstream, this would be your origin remote.
2. Make sure you have an upstream repo added as a remote too. In these
   instructions you'll refer to it by the name upstream. If you don't
   have it, here's how you can add it:

   $ git remote add upstream https://github.com/aio-libs/aiohttp.git

3. Ensure you have the latest copy of upstream and prepare a branch
   that will hold the backported code:

   $ git fetch upstream
   $ git checkout -b patchback/backports/3.8/3e879ec97923e9d29a4a277f942893ae7ed5f090/pr-6178 upstream/3.8

4. Now, cherry-pick PR fix(5432): add query parameters in tracing url #6178 contents into that branch:

   $ git cherry-pick -x 3e879ec97923e9d29a4a277f942893ae7ed5f090

   If it'll yell at you with something like fatal: Commit 3e879ec97923e9d29a4a277f942893ae7ed5f090 is a merge but no -m option was given., add -m 1 as follows intead:

   $ git cherry-pick -m1 -x 3e879ec97923e9d29a4a277f942893ae7ed5f090

5. At this point, you'll probably encounter some merge conflicts. You must
   resolve them in to preserve the patch from PR fix(5432): add query parameters in tracing url #6178 as close to the
   original as possible.
6. Push this branch to your fork on GitHub:

   $ git push origin patchback/backports/3.8/3e879ec97923e9d29a4a277f942893ae7ed5f090/pr-6178

7. Create a PR, ensure that the CI is green. If it's not — update it so that
   the tests and any other checks pass. This is it!
   Now relax and wait for the maintainers to process your pull request
   when they have some cycles to do reviews. Don't worry — they'll tell you if
   any improvements are necessary when the time comes!
