command/show enhancements and bugfixes 

* command/jsonconfig: provider config marshaling enhancements

This PR fixes a bug wherein the keys in "provider_config" were the
"addrs.ProviderConfig", and therefore being overwritten for each module,
instead of the intended "addrs.AbsProviderConfig".

We realized that there was still opportunity for ambiguity, for example
if a user made a provider alias that was the same name as a module, so
we opted to use the syntax `modulename:providername(.provideralias)`

* command/json*: fixed a bug where we were attempting to lookup schemas
with the provider name, instead of provider type.
