If a container has not yet stopped/started we may for proto RESTCONF get "invalid URI" result back for some container actions. With this change we allow the action to be retried up to three times before passing on the error. In tests on Qemu (x86_64) this happens very rarely and need at most one retry before succeeding. Verified by iterating the same basic test over night (9000+ iterations). Fixes #558 Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
