Symlink style credentials

As a credhub user, I would like to be able to have the same credential be available in different paths. To be able use bosh generated variables (/{director_name}/{deployment_name}/{variable_name}) in concourse (/concourse/{team_name}/{variable_name}).

@ramonskie This feels like a workaround to sidestep a limitation imposed by Concourse, rather than a problem that CredHub needs to solve, especially since this exact same use-case (“I need to refer to X value that lives outside my CredHub consumer’s implied namespace”) is supported by BOSH. My suggestion is requesting that Concourse support absolute path references to values in CredHub. If they have a reason why they don’t want to support that, I’d want to make sure adding symlinks doesn’t just recreate some problem they’re trying to avoid in a different way.
