Base class for the server implementation of the service CloudFilestoreManager.
Configures and manages Filestore resources.
Filestore Manager v1.
The `file.googleapis.com` service implements the Filestore API and
defines the following resource model for managing instances:
* The service works with a collection of cloud projects, named: `/projects/*`
* Each project has a collection of available locations, named: `/locations/*`
* Each location has a collection of instances and backups, named:
`/instances/*` and `/backups/*` respectively.
* As such, Filestore instances are resources of the form:
`/projects/{project_number}/locations/{location_id}/instances/{instance_id}`
and backups are resources of the form:
`/projects/{project_number}/locations/{location_id}/backup/{backup_id}`
Note that location_id must be a Google Cloud `zone` for instances, but
a Google Cloud `region` for backups; for example:
* `projects/12345/locations/us-central1-c/instances/my-filestore`
* `projects/12345/locations/us-central1/backups/my-backup`
