Don't mount whole host drive ( "/") into containers

[kilrau]

Is your feature request related to a problem? Please describe.
Mounting the whole host drive into utils, causes issues on several operating systems and is not great from a security perspective. We are currently doing this to be able to check availability of the backup path on start of utils and prompt user to change if not available.

Describe the solution you'd like

• mount backup path only after user entered backup path in flow
• mount .xud-docker path and potentially different network paths as per xud-docker.conf in subsequent step

@kilrau You cannot append new volumes on a running contianer thus why we need to mount "/" into utils.

Aware, so there will be container restarts needed whenever something like backup path or network path changes.

Yes. But we also map "/" into xud container too. So there is no restart required for xud in the past. @kilrau
