Add the functionality of 'tags' into bifrost

[Kim Ng]

We want to be able to create a new item in samples called 'tags' which can be a multifunctional filtering tool. Tags would be saved as a list of strings. Membership in a tag can be used both for pipelines (components) in it's requirement check as well as filtering on the report side (ie only show samples belonging to the tag with this project name. Tags could also be generated from components, for example the QC stamper could assign a tag onto the sample stating it's QC is good.

This item is expected to generate multiple work items.
