Use grpc to improve the CPU utilization of the logging agent.

[bmoyles0117]

Fixes #60762

What this PR does / why we need it:
Using gRPC improves the CPU utilization of the logging agent be reducing
serialization overhead and reusing TCP connections.

Release note:

NONE

[tpepper]

@kubernetes/sig-node-bugs should this be marked for v1.10 milestone?

[bmoyles0117]

@yujuhong I would opt for including this in the milestone as well, as it virtually ensures we will be using less CPU utilization, which should keep us well bounded under the resource requests / limits.
