[FEATURE] create Search Who component

[acharliekelly]

Search component for Who details (Department and/or Officer involved)

Component has two fields, Department and Officer. Both have dropdown auto-complete features.

Department

Officer

Both fields have a "There was another _ involved" link, which will add a duplicate field under the first, which will behave the same way:

Validation (not pictured) should require that at least one field be filled before clicking Next.
Back and Next buttons will continue the search flow.
