Bug 1866265: Stop Keepalived on bootstrap after bootstrap completed #92

When OPENSHIFT_INSTALL_PRESERVE_BOOTSTRAP deployment configuration parameter is set to true the
bootstrap node won't be destroyed and the infrastructure components including Keepalived on the bootstrap continue to run.

With this PR a stop message is sent to Keepalived control socket when the API server is not operational anymore on bootstrap node.
This change is important for platforms that run Keepalived in unicast mode (baremetal).

It's not immediately apparent what "NA" stands for... It's used a few times here, and I sort of get that it's possibly an error condition, but I'm not totally sure from the context. Can we be more explicit here?
