    Move Rails SLI initialization to boot path · a461670e

    This was done lazily because it comes with several
    seconds of delay, since we need to traverse all
    web and API endpoints.
    However, this caused strong coupling between the
    WebExporter and Rails, the former we are looking
    to first extract and then retire.
    Rails boot performance is a known issue, but adding
    the delay does not dramatically increase the
    existing timing at least during local measurements.
    A pending optimization could be to only compile
    Grape routes in the api fleet, but we have no
    mechanism currently for Rails to know which
    workload it serves.
