Implement a way to bypass the transport and use the transfer mechanism (rsync, rclone, etc)

[alaypatel07]

Describe the feature you'd like to have.
#1 implements the network endpoint to allow data to be transferred. #4 adds a transport package that allows for overriding the underlying network protocol. This brings a need for bypassing #4 and using applications like rsync and rclone directly behind the endpoint.

Additional context
The way this was originally thought of was to add a null implementation of the transport interface. The null implementation will make sure that the transfer pod (rsync, rclone) will not have any sidecar containers for network tunneling.
