What is the current behavior? (You can also link to an open issue here)
Allowed operator were defined for all the fields

What is the new behavior?
Allowed types are :

• 'all' = PropertyIsEqualTo, PropertyIsNotEqualTo, PropertyIsLike, PropertyIsGreaterThan, PropertyIsGreaterThanOrEqualTo, PropertyIsLessThan, PropertyIsLessThanOrEqualTo, PropertyIsBetween, During, PropertyIsNull, Intersects, Within, Contains
• 'spatial' = Intersects and Within
• 'basicandspatial' = PropertyIsEqualTo,PropertyIsNotEqualTo,Intersects and Within
  (Default value if none provided)
• 'basic' = PropertyIsEqualTo,PropertyIsNotEqualTo
• 'time' = During
• 'basicnumeric' = PropertyIsEqualTo, PropertyIsNotEqualTo, PropertyIsGreaterThan, - PropertyIsGreaterThanOrEqualTo, PropertyIsLessThan, PropertyIsLessThanOrEqualTo,

Now, we can define the allowed filter type for all fields or at the level field.
