** Is your feature request related to a problem? Please describe.
Apologies for not thinking this through before, but in the same way that FR 695 now allows you to get the revision of a proxy deployed to an environment (and thanks for implementing this so quickly), can we have the same for sharedflows?

** Describe the solution you'd like
Would like the apigeecli sharedflows listdeploy command to allow just the environment and name to be specified. Currently, apigeecli sharedflows listdeploy requires you to specify the environment, name and the revision:

apigeecli -t $TOKEN -o $ORG -e ENV sharedflows listdeploy -n spikearrest
Error: revision must be supplied with sharedflow name and env

Describe alternatives you've considered
As before, the alternative would be to get all sharedflows deployed to the environment and then use jq to parse the JSON output to get the specific sharedflow of interest.
