Squash pip freeze on startup [ENHANCEMENT]

[pandu-k]

Is your feature request related to a problem? Please describe.
The Marqo startup process outputs a lot of text, and we want this to be cleaner.

Describe the solution you'd like
Pip freeze should only be logged if log level is set to DEBUG or higher.

This can be done via an if statement in the run_marqo.sh script.

Screenshots of Marqo's startup, before and after, at the default and at DEBUG log levels, attached to the PR would demonstrate that the feature works as expected.

Additional context

• Documentation for configuring Marqo's log level can be found here
• Pip freeze and logging configuration logic is found in the run_marqo.sh script
  • Pip freeze call
  • Logging configuration logic
  • This is the actual command used to start Marqo.
