run_tests.sh only returns results of last set of tests

Proposal:-
1) either the parallel and sequential tests are seperated into 2 different scripts ( aptly named)
2) the return value after both executions is stored in 2 different variables ( $retvalSeq, $retvalParall) and then we echo the return values (with intuitive commennt/tagline) and exit with the highest return value among $retvalSeq, $retvalParall ? If both or one of them is 0 then i guess we are good since we will get to know the failure/success eitherways. The issue is when both of them have a exit status >0 in that case we are printing the results so that user can see the return values from both (even though we returned only the highest value)

I think 1) is cleaner option since in 2) the case of 2 failures is not handled well but I am not sure whats the convention.

    Add function to catch unknown attributes in URI

    Added a _lookup() function that will catch attribute after {CA_ID}/ in
    the URI that does not match a supported keyword (cacert, intermediates, etc.)
    Before this caused a 500 (server error) to be returned, now the correct
    404 (not found) error is returned.

    Combine exit codes of the two functional test runs

    The script was only returning the exit code of the second of the
    two test runs. With this change, a failure of either either run
    will correctly be reported as an error.
