Closes #9311 Handles container id/name collisions against daemon functionalities according to #8069

Changes truncindex package to properly report when multiple results were found with a given prefix

Modifies Daemon Get method according to the discussion in #8069

Fixes references to Daemon Get throughout. Mostly just ignoring the error message that is now returned, but replacing redundant logic where applicable. These clean-ups could have been more pervasive but I believe they will be easier to carry out once Docker has some notion of error lists defined to replace all of the hard-coded error messages.
Also, I'm not sure about this special errors. I think that this makes sense when you have handlers for errors and here we just returning them. So, maybe will be easy to return from `truncindex` already ready for return errors.
