Adding processing for boolean observations

Current: There is no processing/validation for boolean datatype whereas the openmrs platform/dictionary provides observations with boolean datatype. These observations end up not being mapped on the server side.

Example: An example is the consent observation . Concept id 1710.

Proposal : We propose to map boolean datatype as value coded/iscoded datatype since they map as either 1 or 0.

Opportunity: This enhancement will ensure implementations make use of boolean observations rather than substitute them.
