Adds retry support to Windows AnonDialer
Adds retry support to Windows AnonDialer

Adds retry support to AnonDialer if the pipe does not exist. This will
retry up to the timeout for the pipe to exist and connect. This solves
the race between the containerd-shim-* start command and the
reinvocation.
