Add dev-docs script

[Hodgy]

me: devbot docs biobanks
devbot: biobank docs are here: dev-docs.nottingham.ac.uk/biobanks-docs

Can use the rancher API to query the dev-docs stack and returns similar named services

we'll need to move devbot into rancher (or somewhere else on-prem) so it can hit the private rancher environment, but that's cool.
