Comment 1 for bug 1295609

@James.

I changed local packaging to
    juju-mongodb | mongodb-server
under the assumption that we want to keep the older mongodb for existing envs. The release notes suggests trusty users manually install juju-mongodb *if* they was to bootstrap with it. It appears juju *requires* it for trusty. I think we need separate packaging for trusty that only depends on juju-mongodb.
