Implemented CLI interface to create browser session.

python -m ai.backend.client.cli filebrowser create -v mydata1 -v mydata2

Attach multiple users vfolder to a session.
After successfully starting it prints the url, port number and container id.
Using container id user can destroy the browser session.
python -m ai.backend.client.cli filebrowser destroy [container_id]
Also, WebUI opens in users default web browser tab.

While implementing the filebrowser, I decoupled filebrowser from Vfolder as a separate app.
This will allow having filebrowser its own routing management for more complex commands.
Decoupling will help to improve maintenance and advanced feature implementation of Filebrowser without affecting Vfolder.

Currently there are mypy and pytest difficult issues which were not shown when executing those commands locally.
