Before:

After:

Note that this adds the functionality but we will need to update the qiita-spots:

• qtp-biom,
• qtp-visualization,
• qtp-diversity,
• qtp-target-gene &
• qtp-template-cookiecutter

to actually use this new functionality.

The changes look good to me, only minor suggestion would be to change "can_be_raw" for "is_user_uploadable". Or something that clearly says that a user can upload this artifact type.

Looks good to me, only one minor comment and my endorsement for this feature

[sjanssen2]

is "raw" short for "is_user_uploadable", if so you might want to use it here explicitly to emphasize the filtering criterion
