cli: add --workspace flag to set base directory for Constellation workspace (#2148)
* Remove `--config` and `--master-secret` falgs

* Add `--workspace` flag

* In CLI, only work on files with paths created from `cli/internal/cmd`

* Properly print values for GCP on IAM create when not directly updating the config
