Autoinstall of IG's by ig / canoncial / current (ci-build) support and dev support

[oliveregger]

we have different possibilites to add ig's to matchbox:

1. provide it during startup time
2. upload it in the gui if not disabled by read-only mode parameter httpReadOnly

feature a) specified ig not availabe

what would be nice would be to have for the second option (when not in read-only) mode, that a guide would also get uploaded
when the ig is not availabe:

e.g. validate FHIR IPS document with ig hl7.fhir.uv.ips#1.1.0, if ig hl7.fhir.uv.ips with version 1.1.0 is not yet avaible it would be tried to resolve from the package cache and installed.

feature b) if no ig is specified the ig could be identified with the FHIR Package API

https://app.swaggerhub.com/apis-docs/firely/Simplifier.net_FHIR_Package_API/1.0.1#/default/get_catalog

curl -X 'GET'
'https://packages.simplifier.net/catalog?canonical=http%3A%2F%2Ffhir.ch%2Fig%2Fch-core%2FStructureDefinition%2Fch-core-patient&prerelease=false'
-H 'accept: application/json'

feature c) support for current?

if a validation would be done on the #current version it would check if an updated ci-build version is available and if yes, that updated version should be validated (should that support then also check dependent current dependenciesI). caveat: probably the latest (default) version on matchbox should always be the last published, even though a cibuild would be newer.

feature d) dev support

we have reading support for npm package installed on matchbox, could we extend also the API to upload directly a binary npm package? this would be helpful in CI/CD pipeline to not need to configure the startup parameters.

Feature a) The new config property matchbox.fhir.context.autoInstallMissingIgs allows the server to fetch an unknown IG from the registry (https://packages2.fhir.org/packages/) when performing a validation. Implemented in 4e2ec7a

Feature b) The Simplifier API is queried to find an IG associated with a canonical. Implemented in 8b374a2

Feature c) not implemented yet.

Feature d) The global operation $install-npm-package allows installing an IG by pushing an NPM package through the FHIR API. Implemented in 179dc45
