bmc module does not full implement its api
In the bmc code there are a few items tagged as #TODO. These times either need to be implemented or removed.
Fixes #9711 - bmc module does not full implement its api * adds additional logic around providers * implements /providers, /providers/installed, /host, / * the / returns a list of resources to use to help the user * catches a case where if the provider is nil, we can default to a provider and warn the user * changes the bmc_setup method to be public instead of private. * refactors the providers_installed? rubyipmi command to providers_installed
