We have just 3 scripts (1 soon to be gone because it is unnecessary),
so there is no need to have 2 folders for them.

Some of them are only used by upstream, some are may have been used by us
in the past.
Whatever the reason, we don't need them anymore, so this commit removes them.
This will introduce conflicts when merging upstream but:
- Those conflicts will be easy to solve - just pick our version
- When we move to more granular way of pulling changes we will get rid of
  redundant commits from history. We could even automatically drop commits
  that only touch those files.

No need for them to pollute main directory.

Forum is now the preferred venue for asking questions, this commit
updates our README to reflect that.

It is talking about Datastax CLA, which is not required to contribute to
our fork. Afaik we don't have any CLA required for external contributors
to our drivers.

Updated section about releasing, testing and documentation to match
current tooling and procedures.
Removed some sections that are no longer relevant.

It was copied from Rust Driver repo, with "CONTRIBUTING.md" changed to
"CONTRIBUTING.rst".

This is deprecated and no longer required.

This test verifies that the run method of the loop was called during setUp,
but another test (`class TestTwistedTimer`) was creating and starting the
loop before - and this loop was never stopped.

This commit adds cleanup procedure so that the test works even if loop
was started before.

We don't need them, and its better to remove them rather than
complicate test commands.

test_connection_initialization was fixed in previous commit
test_cloud was removed in previous commit

It's most likely no longer necessary

One of the badges was not working. That's a good opportunity to update them.
Now badges reflect status of master - not latest release - because that
better reflects the state of repository. I also added a badge for
integration tests.
