quota: Fix incorrect keypair usage in show command

Before this change, the 'quota show' command displayed incorrect
keypair usage. While keypairs are listed under compute quotas, the
Nova compute API does not actually gather or track keypair usage data
on a per-project basis. As the result keypair usage output was always 0.

Resolve this by checking whether the current user matches the target
project scope. If the project IDs match, the code queries the compute
SDK directly to retrieve the active keypair count for that user.
