Support comma-delimited values on octopus release deploy --deployment-target command

[KennethBates]

The bug

When trying to pass in multiple targets via the --deployment-target argument in the release deploy command using comma-delimitation, the command fails with the following error.

Octopus API error: There was a problem with your request. [Unable to locate deployment target(s) named 'ABC,XYZ']

Preferably, this should work in the same way the old deprecated CLI can have multiple targets passed via --specificMachines="ABC,XYZ", e.g. octopus release deploy --deployment-target "ABC,XYZ"

Command to reproduce

octopus release deploy --deployment-target "ABC,XYZ"

Outcome

Octopus API error: There was a problem with your request. [Unable to locate deployment target(s) named 'ABC,XYZ']

Workaround

You can still pass a subset of targets by defining multiple arguments in the command, e.g. --deployment-target "ABC" --deployment-target "XYZ"

Versions
