Missing cluster operators json stops log analysis

[abraham2512]

Some jobs such as the Orion job for telco does not have a cluster operators json in its job artifacts. BugZooka attempts to download and fails, and it is preventing log analyzer from downloading orion xmls for further analysis.

Relevant line:

BugZooka/bugzooka/analysis/log_summarizer.py

Line 151 in be21ddf

download_prow_orion_xmls(gcs_path, orion_dir)

This may not need to be contingent on the previous step?
