Setting up and spawning Gitaly in tests needs to have some Bundler
settings configured. Until now this was done by writing to the local
config file in the ruby directory inside the gitaly dir used in test.

This method didn't seem to be robust for all our user and
use-cases (i.e. CI), because this configuration _could_ be done from
different places.

To make the situation more predictable, this change injects all Bundler
configuration through environment variables instead. It sets
BUNDLE_IGNORE_CONFIG to make sure any existing configuration written to
file is ignored, this includes the .bundle/config inside the project and
possibly in the user's $HOME directory.

Tests depend on Gitaly running in the background. There are a few
scripts and libraries that take care of setting up and spawning
Gitaly. These instructions run from different locations in the project
source tree.

Because some people might be specifying the BUNDLE_PATH as a relative
location (i.e. vendor/bundle), the setup step might install gems in a
different location as opposed to where Gitaly-ruby expects them in the
spawn step.

To overcome this, the BUNDLE_PATH is read from the Bundler configuration
and expanded to an absolute path before it's passed on to Gitaly
setup/spawn.
