Handle lint errors in generated serivce code
62a0aea 
This adds the generated VIC service bindings to the ingore
set for linting due to package names containing underscores.
This will present on all but the first build in a given build
env.

Name field is guest visible
1a5aa2e 
The Name field was changed to be hidden from the guest in vmware#4134 to
support docker rename. This was a compromise needed due to an ESX
vigor bug, see vmware#5533.

This *requires* that users be on a version of ESX that has the fix
or bad things may happen to cVM configurations. I have not tracked
down what build versions that entails and have not code a check
mechanism.

This change has the effect of the hostname of the VCH endpointVM
being set to the name of the VCH.
It also allows additional live reconfiguration such as hotadd to
a bridge network, in general modification of all container
configuration live is possible, if not necessarily applied.

I don't think we should merge this as is.
It was a hypothesis for bug2555488 - I've put the shortest path to fix that into the bug report.

This change is not sufficient on it's own. While the guestinfo conversion to volatile issue has been fixed, the semantics are still not correct for what we want. A docker rename will change the name while the VM is powered on, but modifying the value while the VM is powered on overlays a volatile value and when the VM powers off the value reverts. That leaves us with a renamed VM in VC inventory, but incorrectly reporting the old name via docker.
The only option I can see to progress this approach is to have both this guest visible field, and the hidden field that can be modified while VM is powered on, with a check to copy from hidden to read-only that occurs after power off and during endpoint initialization. That's likely too heavy weight for the benefits at this time.

Fixing vmware/govmomi#2000 should be the priority, as without that it doesn't matter what the hostname is set to.
