archive tag is set on source tracks

[smarquard]

This commit:

e4c9d4f

adds the "archive" tag to all source tracks from Galicaster. This is a change from 1.4.x.

In our Opencast 1.6.x workflows, this causes source tracks from Galicaster 2.x to be archived, which is not what we were expecting (by default we archive trimmed tracks, not the source media).

I think this change should either be reverted, or to allow flexibility, add a configuration option like

track_default_tags = archive

(and if blank, no tags are added).

[smarquard]

This can be worked around by adding a workflow step in Opencast to remove the archive tag:

 <!-- Remove archive tags from source for GC 2.x ingests -->

    <operation
      id="tag"
      description="Removing archive tag from source tracks">
      <configurations>
        <configuration key="source-flavors">*/source</configuration>
        <configuration key="target-tags">-archive</configuration>
      </configurations>
    </operation>

@smarquard Our work here has been added to the 2.1.0 release. Now by default Galicaster does not add any tags, and there is an optional profile configuration value to include tags for each track (the parameter is 'tags')
