MLCOMPUTE-2001 | Skip UI port selection, pod tpl generation, and logs for driver on k8s tron

[chi-yelp]

Did the following changes to reduce unnecessary noise from Spark jobs in the Tron deployment logs:

• Allow passing in a constructer flag is_driver_on_k8s_tron to SparkConfBuilder
• When is_driver_on_k8s_tron is true:
  • Skip Spark argument deprecation warnings
  • Skip trying to pick an available ephemeral port (always use the first port for the driver pod)
  • Skip generating pod template

(There will be a follow up PR in the paasta repo)

Test: build and install the package in the paasta repo
