[Workspace] Add workspace list page

[raintygao]

Is your feature request related to a problem? Please describe.

When user wants to view all workspaces, he has to use dev_tool to call restful API to search manually. This is inconvenient. There should be a new page that can display all workspace lists and contain general information and support search.

Describe the solution you'd like

We would build a new page named 'workspace list page', this page will support contain a table that displays all workspaces and displays the name, id, description and features of each workspace. This table will support search specific workspace through name and contains two operation button on workspace, including delete and edit.
