project.conf: Set the artifact cache URL heresam/bst-artifacts-url

This is possible since this change: https://gitlab.com/BuildStream/buildstream/commit/00e08459c4

Older versions of BuildStream will fail to parse the project.conf file
with this change; I think it's acceptable to force everyone to update
as we are still in the development stage of the BuildStream migration.

If you want to override the configuration for whatever reason you'll
now need to put this in your ~/.config/buildstream.conf file:

    projects:
      baserock:
        artifacts:
          pull-url: ...
          push-url: ...

If you set a "global" artifacts configuration by doing this...

    artifacts:
      pull-url: ...

... it'll be ignored because the project-specific config from this
project.conf file will take precedence.

Overriding seems to be done for the whole config block, so if you
only set push-url in your buildstream.conf file it will be interpreted
to mean "set push-url, and unset pull-url" rather than "set push-url
and use the existing value of pull-url."
