Improve Readability and Maintainability of truss_handle.py

[AmadouO20]

Problem:
The truss_handle.py file has become difficult to read and maintain due to its complexity. To ensure the future of the codebase and to make it easier for new contributors/users to understand the file.

Proposed Solution:
Refactor Code into Smaller Functions
Adhere to Coding Standards: such as PEP 8 standards

Alternatives
Another alternative is FLAK8 and reduce the length of some lines.

Additional context
For example, the function docker_run in truss_handle.py can be refactored as it has >100 lines.

@marius-baseten - any chance I can take this ticket?

Hi @sumerjoshi, we are in the middle of making some bigger architectural changes to Truss, so this is much lower priority now (we don't have bandwidth to help with this either). Thanks so much for offering though!

@squidarth - thanks for the response. I'm pretty excited about ML (especially ML infra). Love the product and how fast the team iterates...
