Enable dynamic typeahead filters

[#1]

Description - Typeahead fields are essential for maintaining data relationships.  Enable the current filtering functionality to also respect dynamic filters (like other parts of Workfront).

Why is this feature important to you -

Currently a typeahead field can only filter to a hard coded filter (ex: portfolioID=12345).  The challenge with typeahead fields is that they can have tons of possible options - many of which may not be relevant to a given scenario.

How would you like the feature to work -

Enable dynamic filters (ex: portfolioID=DE:Custom Field)

This would allow us to dynamically filter the results based on an attribute on the project - leading to cleaner data and easier experience for end users.

Current Behavior -

It returns erroneous results.
