Compute API v1: xxxResourceName.parse throws ValidationException

[dtretyakov]

Currently all parse() methods in xxxResourceName classes expect that input string will be formatted like projects/{project}/..., but data returned from APIs contains URL prefixes like https://www.googleapis.com/compute/v1/projects/... and as result parsing fails with ValidationException.

Example

Receive instance details where:

instance.zone = https://www.googleapis.com/compute/v1/projects/project-123/zones/europe-west3-c

Then when trying to parse it with ProjectZoneName.parse(instance.zone) will cause the following exception:

ProjectZoneName.parse: formattedString not in valid format: Parameter "https://www.googleapis.com/compute/v1/projects/project-123/zones/europe-west3-c" must be in the form "projects/{project=*}/zones/{zone=*}"
