In LSST catalog and image search, we need the feature, All Sky, to allow user to input query requirement(s) without giving a target. Need to implement the search processor(s) to support this.

The following items will be added to implement this request:

[LZ Feb-9-2017]

1. Add a test to see if the search method is "allSky" In the getSearchMethodCatalog method
2. Add the same test if the search type is "allSky" in the getMethodOnSearchTyp method
3. Add the code to guard the user error when click search without any constraints in all sky search. When such case happens, it will throw an EndUserException with error message.
