csm_install doesn't work

[niks3089]

The code assumes the csm_install is only for local projects :

    if (command.startsWith('csm_install') || command.startsWith('csm_update')) {
      return await csmInstallOrUpdate(command);
    }

Hence regular command-sets from our github repo cannot be installed:

 nc> csm_install awsbill
Error: Path /Users/nikhil/projects/nimbella/awsbill doesn't exist.
 nc> csm_install gcloud
Error: Path /Users/nikhil/projects/nimbella/gcloud doesn't exist.
