Show all the internal information in Providers accordion

[igor-ka]

Instead of handpicking which information to show for each of the built in providers as well as ignoring certain providers (like custom directives), show all of the information pertaining to the provider tokens.

For example:

1. In the Kitchen Sink Demo app click Form Component section
2. Select one of the input elements on the section of the component tree that appears
3. Expand the Providers accordion and note the information shown there.
4. Go to the console and input the following $a.injector.get($a.providerTokens[3]), this will show the information that corresponds to the NgControlName provider.
5. Compare the information on the console with the information under the Providers accordion for the same provider.

We should shall ALL the information for each of the providers, i.e. should show all the same information as is shown on the console.

This issue was added as a result of investigation performed under investigation #648 and will support custom directives.

After taking a look at this information, and trying to serialize it, I've concluded: It would be a pretty big investment of time and effort to serialize most of this information in a generic way. It would be a much bigger investment of time and effort to display it well, as it means writing something similar to the state tree (but less tied to editing component state).

As a result of this I think I should prioritize work that I find more feasible. It is possible that a fresh set of eyes could solve this more easily.

@xorgy I will take a look at this as well and then we can discuss how do we approach this and prioritize this one.

@sumitarora @xorgy thank you. we can revisit this in the next milestone and focus on higher value stuff for now.
