Improve CI run time #2215

What does this implement or fix?

Builds on top of the PR to improve the build times by using sccache on S3: #2208

This PR improves the test execution by:

using xdist to run tests in parallel
extending the lifetime on the main fixtures to prevent unnecessary creation of buckets and etc. which are quite expensive on Windows
Moving some tests out of integration to other types (e.g. compat) to balance the time spent on integration tests
improving some of the tests to use batch operations instead of regular reads/writes when those are used for setup/checks

These changes improve the total run time of the CI to ~1h (down from ~3h)

Also a couple of very slow tests have been marked as slow to enable faster local testing.
When running all (incl. those that use simulators) of the non-slow tests locally with the following command:

ARCTICDB_RAND_SEED=$RANDOM ARCTICDB_DISABLE_SLOW_TESTS=1 pytest -n auto tests

Runs about 9000 tests in under 10 min (down from ~60 min before).
Which makes the experience of running the tests locally much better.

Any other comments?

Why have you removed this? Might make @vasil-pashov sad

sccache doesn't work with precompiled headers, so this is making the build much slower on Windows.
AFAIK this is used only in the CI, I am correct @vasil-pashov ?

Confused, why can't we just always supply the heartbeat?

I am greatly reducing the frequency of the heartbeat because we don't really care about it in the testing.
But it is still needed for actual usage of mongo, so better to keep it to the default value.

Should also have arctic_library_v2 right?

Currently we are testing with both v1 and v2 by default.
This new fixture is so we can reduce the number of we can reduce the number of tests which don't really care about the encoding - mainly for the tests that check if we can create library/symbol with a given name.
These tests are quite slow (they have to create/write 100s of libraries/symbols) but are not really affected by the encoding.

If we every need to test only v2, we can add it but this is not needed at the moment.
