*: Remove "bundle" and go straight to config.json

Some history behind bundle requirements:

* 77d44b1 (Update runtime.md, 2015-06-16) lands the initial reference
  to a root filesystem, requiring a relative path.  It also lands the
  "bundle" construct, which at this point includes content
  directories, signatures, and the configuration file.  The content
  directories "at least" include the root filesystem.

* 5d2eb18 (*: re-org the spec, 2015-06-24) shifts the bundle docs to
  bundle.md and demotes signatures to "other related content".

* 91f5ad7 (bundle.md: various updates to latest spec, 2015-07-02,
  opencontainers#55) finishes the signature demotion and strengthens the
  root-inclusion requirement with another "must include".

* 7232e4b (specs: introduce the concept of a runtime.json,
  2015-07-30, opencontainers#88) split out runtime.json, required the root directory
  to exist at `rootfs`, and dropped most references to "content
  directories".

* 106ec2d (Cleanup bundle.md, 2015-10-02, opencontainers#210) kept the requirement
  for a rootfs directory in the bundle root, but relaxed the name
  requirement to allow other single-component names
  (e.g. `my-rootfs`).  Dropped the last reference to "content
  directories".

* cb2da54 (config: Single, unified config file, 2015-12-28, opencontainers#284)
  rolled runtime.json back into config.json.

* b2e9154 (Remove requirement for rootfs path to be relative,
  2016-04-22, opencontainers#394) allowed absolute paths for root.path and removed
  some "same directory" language while leaving other "same directory"
  language.

I think the root filesystem should be optional [1], but even folks who
disagree on that point have come to the conclusion that it doesn't
need to be in the bundle [2].  opencontainers#394 seems partially unfinished, but I
think the intention was clear.  Once you relax the "bundle must
contain the root filesystem" requirement, the only thing that the
bundle must contain is config.json.  It doesn't seem to be worth the
trouble to name a "bundle" construct if its only meaning is "the
directory that holds config.json", so this commit removes all
remaining references to the term "bundle".

 Standard Containers are INFRASTRUCTURE-AGNOSTIC: they can be run in any OCI supported infrastructure.
-For example, a standard container can be bundled on a laptop, uploaded to cloud storage, downloaded, run and snapshotted by a build server at a fiber hotel in Virginia, uploaded to 10 staging servers in a home-made private cloud cluster, then sent to 30 production instances across 3 public cloud regions.

 ## 4. Designed for automation
 
 Standard Containers are DESIGNED FOR AUTOMATION: because they offer the same standard operations regardless of content and infrastructure, Standard Containers, are extremely well-suited for automation.
 In fact, you could say automation is their secret weapon.
 
 Many things that once required time-consuming and error-prone human effort can now be programmed.
-Before Standard Containers, by the time a software component ran in production, it had been individually built, configured, bundled, documented, patched, vendored, templated, tweaked and instrumented by 10 different people on 10 different computers.

 Builds failed, libraries conflicted, mirrors crashed, post-it notes were lost, logs were misplaced, cluster updates were half-broken.
 The process was slow, inefficient and cost a fortune - and was entirely different depending on the language and infrastructure provider.
