Fixing ValueSet expansion not supporting canonical url. (#3501) 

* 2991 - WIP, starting to implement test to reproduce the issue.

* Adding capability to extract url & version from the valueSet.include.url

* parsing codeSystem canonical URL to extra version if required.

* WIP

* Cleaning up the test.

* Replacing hard code value with variable.

* Removing non required test.

* Modifications following first code review.

* Further modifications following first code review.

* Refining the test for better code coverage.

* Prefixing the change log file name with the hapi-fhir issue number.
