install catalog for this package doesn't conform to openwhisk-catalog

the installation script for this catalog is different and doesn't reuse any of the utils from the openwhisk-catalog --- this is bad because it means one needs a completely different process to install this catalog (locally) compared to the other package.

for better or worse, all our packages should follow a standard process for deployment. so we should have only one (whether it uses the pattern here or in the other repo), and make every package adapt accordingly.
