Sync error when ingress name has dots

[mcfedr]

Its valid for kubernetes resources to have dots in the names, so an ingress with a name like some.host.com-ingress is valid, but the gce ingress fails when you create such an ingress, with an error like

Error during sync: Error running load balancer syncing routine: googleapi: Error 400: Invalid value 'k8s-um-default-some.home.com-ingress--521bdf95908d2d0'. Values must match the following regular expression: '[a-z](?:[-a-z0-9]{0,61}[a-z0-9])?', invalidParameter

This mismatch of valid values could be handled by the controller

We may elect to not fix this as the munging the dots into underscores in the name can result aliasing issues for the GCP objects, unless there are a lot of users in this situation...

For tracking purposes, marking this as a bug but as bowei said, we may not fix this.

Fair enough, i thought that might be the case, but still useful to know about it and for others to be able to find it.
