libzds: add curl interface to access zosmf rest api

Browse Source 
Add library functions that allow to communicate with z/OSMF REST services
using libcurl.
Following three functions are added:

lzds_rest_get_enq()
	to obtain an ENQ that will mark a dataset as in use to z/OS until
	it is released again
lzds_rest_release_enq()
	to release an ENQ and mark a dataset as no longer in use to z/OS
lzds_rest_ping()
	to ping a z/OSMF REST server to check if it accessible
	or to refresh an ENQ and prevent it from a timeout after 10 minutes
