Doublestar support in mount array

[PaulRill00]

Is your feature request related to a problem? Please describe.
When working with mono-repo's caching dependencies might be tedious. So instead of mounting every subfolder and it's dependencies, allow for generic folder selection.

For example, if one has a folder structure like:

root
  package.json
  node_modules
  packages
    package1:
      package.json
      node_modules
      dist
    package2:
      package.json
      node_modules
      dist

Let's say you want to cache all node_modules and dist folders, without having to require all those folders in the mount array separately.

Describe the solution you'd like
Support generic folder mounting like:

mount:
  - "node_modules"
  - "packages/**/node_modules"
  - "packages/**/dist"

A dependency that might help solve the issue: https://github.com/bmatcuk/doublestar

Describe alternatives you've considered
You could also go with a regex alternative, but the one above seems more straight forward.
