We've changed the config to be more consistent about "copies" and
"artifacts". This means that "copies" no longer accepts a string, but a
slice of strings. We should bump the config version and blubber version
to make it clear that we're not longer backwards compatible.

Uses the github.com/ghodss/yaml library to convert YAML to JSON before
unmarshaling for the purposes of supporting YAML and JSON input while
converting to only support JSON internally.

All import paths and other references to the previously Blubber repo in
Phabricator have been changed to point to the new Gerrit project URL.
Note that building or testing against this change will require you to
move your working directory to `$GOPATH/src/gerrit.wikimedia.org/r/blubber`.
Contribution documentation was updated to reflect the changes, and the
`.arcvendor` submodule has been removed.

Summary:
Since `config.Validate` was changed to take any interface as an
argument, many of the validation tests can be refactored in a way that
avoids having to parse the full config context in YAML and instead
validates each specific config struct directly. The new test pattern is
simpler and less prone to future breakage should unrelated parts of the
overall config change.
Tests that rely on root config context were left unchanged.
Test Plan: Run `go test ./...`.

Summary:
Introduced a `version` config field that must be specified and match
`config.CurrentVersion`.
Changed `config.ReadConfig` to use `yaml.UnmarshalStrict` to ensure that
errors are surfaced when unknown/bad fields are present in the given
YAML config. A smaller `config.VersionConfig` is now unmarshaled first
to prevalidate the new `version` field before the entire config is
parsed.
Fixes T191460
Test Plan:
Run `go test ./...`. Run `blubber` against some configuration containing
invalid fields and ensure that it surfaces a YAML error.

Summary:
Introduce new `build.EntryPoint` and `build.WorkingDirectory`
instructions to allow configuration to inject them instead of hard
coding their generation in the Docker compiler.
Simplified the Docker compiler to simply iterate over build phases as
returned by a new function `build.Phases()`.
Depends on D990

Summary:
Introduces new `lives` configuration that provides the name/UID/GID of
the user that will own application files and installed dependencies.
This new configuration is distinct from `runs` in that the former
determines application file location ownership and the latter now only
determines runtime process ownership. Default configuration has also
been introduced for both config sections.
In addition to the new configuration, a new `build.CopyAs` instruction
has been introduced that ensures correct UID/GID ownership of files
copied into the container image, and all unqualified `build.Copy`
instructions are wrapped by the new `build.CopyAs` instruction using the
UID/GID appropriate for the current build phase. A new `build.User`
instruction is also introduced and injected into the build at the start
of certain phases to enforce ownership of `build.Run` processes.
This effective process/file ownership model is:
PhasePrivileged - "root"
PhasePrivilegedDropped - lives.as
PhasePreInstall - lives.as
PhaseInstall - lives.as
PhasePostInstall - runs.as
