UgandaEMR: Use cases for the Data Filter module

@wyclif @ibacher Can we use the data-filter to filter out some form fields tagged too sensitive?

Sample use case:

A psychiatrist, will capture all observations, including the most sensitive ones in a form, but a counselor should not see fields marked as “too sensitive”.

FYI, I am aware that this requirement is also achievable using privileges and the form buildershideWhenExpression like

“hideWhenExpression”: "isUserHavingTooSensitivePrivilege()"

However, we wish to explore this use-case using the data-filter if possible.
