Add filtering for workspaces

[apinkert]

For RHCLOUD-35021. After speaking with @karelhala, we decided the other filters were not necessary for this PR (creator hasn't been implemented yet and parent search was redundant).

From our conversation:

• A filtered workspace should show its parents
• A filtered workspace should not show its children
