As a user, I can import multiple projects using the ALM/QC importer

The ALM/QC importer only allows to import one ALM/QC project at a time.

However, this can be a bottleneck for uses wishing to perform a mass migration from ALM/QC.

It should be possible to import multiple projects in bulk using the built-in ALM/QC importer.

ACs:

• All available ALM/MC projects should be listed and a user can select one or more project, or all of them, to import at once/in bulk
• It should be possible to perform a quick search/autocomplete to select the project, to facilitate selection of projects
