Add links and rep in the response for the collection

Add links and rep in the response for the collection

- Use common ExtractParamFromQuery in ocresource and occollection to extract query parameters.
- Added links tag to the oic.if.ll and oic.if.baseline.
- Added rts tag in the payload for the baseline. - Added rep tag for oic.if.b response.
- occollection was using extra structure to differentiate ll, baseline, batch and group. Simplified the code to use
a simpler code and removed unwanted structure.
- oic.wk.col added in the types.
- OCStackIfTypes is removed as it was used only internally. This is not needed due to usage of ExtractParamFromQuery.
- BuildResponseRepresentation is updated as it is used in collection. For inner payload, these
values were not being used by ocpayloadconvert.
- oic.if.ll has been updated to give response in form of {links:[{href:"", rt:[""], if:[""]}]}
- oic.if.baseline has been updated to give response in form of {rt:[], if:[], rts:[], links:[{href:"", rt:[""], if:[""]}]}
- oic.if.b has been to response in form of [{"href": "", "rep": {""}}]
- in case of wrong query it will respond with error message.
