Support removing tags from resources

[nicwells]

Fixes BlueBrain/nexus#2934

Description

A dropdown button has been added to the resource advanced view tab. In the dropdown it lists the tags that exist on the resource along with the associated revision. Clicking on one of the tabs will display a confirmation message requiring the user to confirm their intention to remove the tag. The button is displayed only on the latest revision of the resource.

How has this been tested?
