Add support to map Azure Boolean Fields to Aha

This request is to support the mapping of ADO boolean fields to Aha predefined droplist and tag fields.

Currently, Azure DevOps Boolean fields (true/false) cannot be mapped to Aha fields. Rather, in ADO, you need to create a field as a picklist in order to have a 2 way mapping to Aha. Our pre-existing ADO environment has a significant number of boolean fields, especially since they display much better on screen, and cannot be mapped to Aha. This would require me to change all boolean fields in ADO to be a picklist and convert all existing boolean fields.
