Implement schema list page

[kgodey]

Problem

Users should be able to create a new schema, edit schema names, and delete schemas.

Proposed solution

We should provide a way to do these actions from the UI using the schema list page introduced in the design spec.

Additional context

• Allow users to edit schema names via the API #166
• Allow schema deletion via API #168
• Design for working with schemas #170
• Allow schema deletion and renaming via the API #393

Marking as ready because we already have listing and creation APIs and that's enough to get started. This will be fully unblocked once #393 is merged.

As part of this issue, a new route has to be created for schema listing, and only the content of schema listing page is to be developed. We have another issue #362 which handles the changes in the top navigation bar.

In order to facilitate development independently, we can have a placeholder button to navigate to the schema listing page, as part of the PR for this issue.

@dhruvkb How's this coming? Do you need any help?

[dhruvkb]

I'm working on it. I should be able to wrap this up during the upcoming weekend as I didn't get much time during the last.

Sounds good, thanks!
