Allowing multiple ways to create or join workspaces

[zjkmxy]

After the user click the ADD button on the Workspace page, there should be a selection page allowing users to choose:

• Create a new workspace
• Join an existing workspace by manually input credentials
  • Should also provide ways to create key pairs, so users do not need ndnsec.
• Convert a connection certificate into a workspace certificate

Also, there should be a page allowing users to enroll another user.

Updates:

• Conversion is provided. Though the button is too large.
• (Initiator-only Mode) Create new workspace: the initiator should be able to issue certificates within the workspace App.
• Joining by QR code is still not working. First, there is no QR code to scan for safebag (no tool generates such a code). Second, the QR code page is very unfriendly on a mobile device.
