[FR] Add possibility to pass a -f JSON file to apihub deployments create #680
Description
Is your feature request related to a problem? Please describe.
I need to pass a JSON deployment definition to apigeecli apihub deployments create, but can't pass a -f file currently, only a subset of fields as CLI params.
Describe the solution you'd like
Support for a -f file input for the apihub deployments create method, similarly to versions create.
Describe alternatives you've considered
Alternative currently is to use the API hub API directly if apigeecli doesn't support this, however -f is supported for other apihub operations, so it would great if it was supported here too.
