Added
- `CustomAsyncExecutor` added with analogous examples to `CustomExecutor`.
- Tests for this executor were also added.
- `.gitignore` added similar to other executor repos.
Changed
- `CustomExecutor` is now updated to reflect latest changes made to `BaseExecutor`.
Fixed
- Tests file name changed from `**tests.py` to `**test.py` as it wasn't getting detected by pytest earlier.
- Duplicate entry of `pytest-asyncio` in requirements fixed.
