[CLIENT-2239] CI/CD: Use massif to get Python client memory usage over time while running integration tests

[juliannguyen4]

Removed pytest-memray test, since it's not needed for CI/CD regression testing; only for debugging

Note: Did not test the last commit: Show massif output even if tests failed

Testing:

Metrics code has a memory leak. Massif does show increased memory usage (double that of dev): https://github.com/aerospike/aerospike-client-python/actions/runs/10706083490/job/29682962437#step:12:19
Run on dev: https://github.com/aerospike/aerospike-client-python/actions/runs/10690461665/job/29634968764#step:13:20
Can still run memcheck. No regression in ci/cd code: https://github.com/aerospike/aerospike-client-python/actions/runs/10690463167/job/29634968672
