Allow querying capabilities matching a given qualifier pattern that contains asterisks

[danielwiehl]

Is your feature request related to a problem? Please describe.

The manifest registry does not support query capabilities from a micro frontend using asterisks in the qualifier pattern.

Describe the solution you'd like

ManifestRegistryService#capabilities$ should support to query capabilities that match a given qualifier pattern that contains asterisks. It should be possible to specify the asterisk as qualifier value and also as qualifier key, e.g. '*': '*'. The latter should return all capabilities matching at minimum the given qualifier pattern.
