[FEATURE REQUEST] Consistency command structure between `service acl` & `service acl-entry`

**Is your feature request related to a problem? Please describe.** `service acl describe` accepts the name of the Service, Service Version, and ACL name. ``` fastly service acl describe --service-name $SVCNAME --version latest --name $ACLNAME ``` However, `service acl-entry list` requires the ID of the ACL. ``` ./fastly service acl-entry update --service-name $SVCNAME --acl-id=$ACL_ID ... ``` **Describe the solution you'd like** Usability would be improved with support for writing it this way: ``` ./fastly service acl-entry update --service-name $SVCNAME --version latest --acl-name $ACLNAME ... ``` (applies to the other acl-entry commands as well) **Describe alternatives you've considered** Use `fastly acl describe` to get the ID and then script the next command.
