Swagger: fix inconsistencies (try #2)

As I've mentioned once or twice, hand-maintained swagger docs
are evil. This commit attempts to fix:

  * Inconsistent methods (swagger says POST but code signature
    says GET)

  * Inconsistent capitalization

  * Typos ("Mounter", "pood")

  * Completely wrong paths (/inspect vs /json)

  * Missing .Method() registrations

  * Missing /libpod in some /volumes paths

  * Incorrect method declaration: /libpod/containers/.../kill
    was correct (POST) in swagger but wrong in the code itself
    (http.MethodGet). Correct the latter to MethodPost

This is two hours' work, even with a script I have that
tries to cross-check everything.

Swagger docs should not be human-maintained.
