Remove large database files after every test suite (#3090)

Browse Source 
Closes https://github.com/neondatabase/neon/issues/1984 
Closes https://github.com/neondatabase/neon/pull/2830

A follow-up of https://github.com/neondatabase/neon/pull/2830, I've
noticed that benchmarks failed again due to out of space issues.

Removes most of the pageserver and safekeeper files from disk after
every pytest suite run.

```
$ poetry run pytest -vvsk "test_tenant_redownloads_truncated_file_on_startup[local_fs]" 
# ...
$ du -h test_output/test_tenant_redownloads_truncated_file_on_startup\[local_fs\]  
# ...
104K    test_output/test_tenant_redownloads_truncated_file_on_startup[local_fs]

$ poetry run pytest -vvsk "test_tenant_redownloads_truncated_file_on_startup[local_fs]" --preserve-database-files
# ...
$ du -h test_output/test_tenant_redownloads_truncated_file_on_startup\[local_fs\]  
# ...
123M    test_output/test_tenant_redownloads_truncated_file_on_startup[local_fs]
```
