Promoted tags are visually different from User tags (green color)
Promoted tags can be added one at a time similar to how tags are added in CDAP today
Promoted tags can be added as a list or uploaded as a text file
When a user tried to add a tag to a dataset, as they type, a list of tags is displayed along with a count of the number of datasets using that tag. Preferred tags are displayed first and in a different color.
All tags are sorted by usage when user is typing (most used first).
When someone uploads a list that also contains user tags, those user tags are promoted to promoted tags.
Before preferred tags are uploaded, a confirmation dialog is displayed to the user indicating the number of tags that will be added. If some tags failed to be added, this number will be less than the number of lines in the file.
