Add user_id and project_id to snapshot APIs

In a cloud with multi-tenancy, administrators
would like to see the project_id of the tenant
while listing snapshots of all tenants.

Likewise, we also should expose the user_id field
as it would help in cases where tenants have multiple
users.

DocImpact
User and administrator references need to capture
this information.

APIImpact
API changes are micro-versioned.
