Support containerized workloads to remove the need for elevated permissions

[hsubramanianaks]

This is a feature to support containerized workloads which would run user's workload in containers like docker and local agent would run in the same container/ same network using docker compose. Port forward happens from user's workload to local agent to remote agent running the k8s cluster and vice versa.

Pros:

• Eliminates the need of elevated permissions
• Doesn't harm local machines configurations
• Resolves conflicts with services already running in any port which B2K might allocate ex: port 80, 443.

Cons:

• user workloads need to be containerized in local, ex: running in a container in docker
• use of devcontainer.json is required to make this work. sample PR here and about devcontainers for vscode here
• Find an alternative way to solve this for VS users - In progress.
