Make unnamed volume names more unique

[davidfowl]

Description

• Follow a scheme similar to what we do for persistent containers. Use the first 10 characters of the SHA256 of the app host's physical path as the volume name prefix.
• This is a breaking change and the only workaround is the manually specify the volume name.

Fixes #5413
