Mount local FHIR cache

[cybernop]

Contributor Pull Request

Mount local FHIR cache instead of each devcontainer having its own FHIR cache.

Description

Mounts the user specific FHIR cache from ~/.fhir/packages into the dev container at /home/vscode/.fhir/packages. The home directory on the host system is determined using OS environment variables for Windows and *nix and MacOS. By mounting only the .fhir/package sub-directory instead of the whole .fhir directory, container specific FHIR configuration like for codfsh will still be separated for each container.

Motivation and Context

By not having each devcontainer have its own FHIR cache, the required storage space is reduced, and packages don't need to be re-downloaded and inflated again and again.

How has this been tested?

Tested on my local Linux machine and was also used in previous projects on a Windows machine.
