Remove all lines between Builder & Depot
Remove all lines between Builder & Depot

* Hab CLI has had it's documentation updated to reference Builder
  instead of the Depot. This is primarily present in any commands
  which accept a `--url` and/or a `--channel` flag
* `HAB_DEPOT_URL` renamed to `HAB_BLDR_URL`. We will still honor
  `HAB_DEPOT_URL` but it is no longer present in documentation
* `HAB_DEPOT_CHANNEL` renamed to `HAB_BLDR_CHANNEL`. This is
  still supported the same as `HAB_DEPOT_URL`
* The value of `--url` or `HAB_BLDR_URL` no longer expects a path
  portion of the URL. For example, you no longer need to specify
  `--url http://localhost:9636/v1/depot`. This was leaking the API
  version and it's API in the CLI causing issues for clients which
  were to be configured to speak to a non-public Builder endpoint
* Large portions of the documentation have been updated to reference
  Builder as an entity. Documentation about the "Depot component"
  has not been altered but it should be given a refactor
* Builder-Web configuration no longer expects a url containing a
  path. This is identicle to the changes to the value of `--url` on
  in the CLI
* Renamed "Depot" to "Builder" on Builder-Web
