Ability to set file mode for inline files.

[GrahamDumpleton]

Describe the problem/challenge you have

I want to be able to do:

apiVersion: vendir.k14s.io/v1alpha1
kind: Config
directories:
- path: packages/example
  contents:
  - path: .
    inline:
      paths:
        script.sh: |
          #!/bin/bash
          date

where script.sh needs to have execute file mode permissions when created.

At the moment it is always created with only rw- permissions.

Describe the solution you'd like

Like how in Kubernetes when mounting config maps it is possible to specify a defaultMode with a umask, would like something similar.

apiVersion: vendir.k14s.io/v1alpha1
kind: Config
directories:
- path: packages/example
  contents:
  - path: .
    inline:
      paths:
        script.sh: |
          #!/bin/bash
          date
      defaultMode: 0755

Anything else you would like to add:

It is a bit annoying that this can't be specified on a per file basis, but a default mode for all paths is better than nothing. One can always segregate files that need to be executable under different array item under contents.

Adding this here and not as a separate issue as falls under same umbrella, but this ability to set file mode also needs to apply to files introduced from secrets or config maps using inline.pathsFrom.

apiVersion: vendir.k14s.io/v1alpha1
kind: Config
directories:
- path: packages/example
  contents:
  - path: .
    inline:
      pathsFrom:
        secretRef:
          name: my-scripts
      defaultMode: 0755
