Remove test configurations in tests/resources

[Qian-HuiChen]

Remove all configurations stored in tests/resources which are used in unit testing.

Instead, on-demand cloning is called via git clone during unit test execution and cleaned up after the unit tests. A fixed commit hash is currently hard-coded in tests/common.py to ensure reproducibility and version control.

Closes #117.

Thanks for implementing this @Qian-HuiChen. It is nice to see so many deleted files :)

As the cloned configurations are used in several tests, an option could be to have a session-scoped fixture that creates a cache of the cloned configurations. Then a test-scoped fixture that copies the clone to a tmp directory, and then cleans up the directory after. This might run faster than cloning for every test.

The fixture implementation looks neat! The latest commit does speed up the tests :) On my local laptop, the tests in 9595035 took about 90s to run and now in 7a19ac6, its about 45s

Both my comments on code are minor and can be left, but it would good to reduce the size of the test esm1.6's access.out file if possible, as it's a large file to add to the repository.

I tried to trim down esm1.6/output000/access.out in commit 7afe6ef.

Thanks @Qian-HuiChen, looks good to me :)
