[Internal] [Feature] Refactor submission scripts so that each python script from seqsender is a separate local nf process

[kyleoconnell]

Currently initial submission and update submission are handled by run_submission.py. Consider breaking these into two separate nf modules.

Place an ❌ in a Box that Best Matches the Feature's Importance:

• [] 1 - Most important (absolutely integral and will not use codebase at all without it)
• 2-4 - Moderate (still using codebase for other functions but is serving as a blocker for future use-cases)
• [] 5 - Least important (would like to see but there are no stringent expectations nor urgency for current/future use-cases) 

Any Additional Context or Information? Has There Been Any Progress Made So Far Towards this Request? Any Helpful Resources to Reference? Screenshots or Links?
