rework several worker roles

[obi-bot]

clinical research coordinator role
contract research organization role
proxy respondant role
sub-investigator role
these roles are not used by the community. the community does use pathologist role, role of pathology review board, but these will probably not be used within OBI. they can be deleted or kept at your discretion.
