Move hard-coded path in E2E benchmarks to config json

[efajardo-nv]

Description

• Move hard-coded glob (inside MORPHEUS_ROOT) for CloudTrail AE training data to e2e_test_configs.json.
• Fix CloudTrail AE training data glob to point to training data instead of validation/inference data. This will result in longer pipeline run times because training data used by pipeline will now be larger.

Fixes #1005
