Fix build issues

[LTA-Thinking]

Description

Fixes two issues failing builds:

• Builds are timing out on unit tests due to the Reindex Orchestrator tests. They will be skipped while they are being reworked.
• Retries of the SQL server creation step fail due to the firewall rule already existing. This adds a check for if the rule already exists.
