Add ability to override the container name instead of base in kubernetes executor

### Description

There is no way to override the container name for the jobs launched by kubernetes executor; this makes observability per job level super hard as per the OTel specifications for monitoring.

### Use case/motivation

We want to have granular monitoring over each job per the kubernetes metrics, otel traces and log collectors.
