The tags support feature can be divided into the following sub-tasks

• Create models to support tags
• Modify frontend to support view of tags for samples as well as regression tests
• Modify frontend to add a search dropdown and button based on tags
  NOTE: This is in working state but design improvements and implementation is pending
• Create backend support to query regression tests and samples based on tags
• Create an "All Categories" option to view all regression tests (This is not supported currently)
• Make subsequent filter and API calls from frontend to enable queries based on tags
• Create a way to easily support managing of tags on samples

Core functionality: Filtering regression tests via tags

Core functionality: Adding tags on existing samples and creating new tags in a easy way

Core functionality: Showing tags on sample info pages

Smaller improvements: Showing tags on samples via regression tests and adding an edit button to edit the samples
