#### What this PR does / why we need it:
This PR adds frontend support for checking whether an slug already exists when creating posts.
Note:
1. The current implementation isn’t perfect, some actions (like clicking the “Publish” button) don’t check for duplicate slug yet.
2. Slug checking in the user center might not be accurate, since it may not have permission to query all posts.
