cells: hypervisor API extension can't find compute_node services

[Andrew Laski]

After the conversion to use Service objects in the hypervisor API extension the lookups for services are happening in the parent cell, not the child cells. This is due to cells redirects not being implemented in the Service object.

[John Garbutt (johngarbutt)]

don't think we should block the kilo release on this bug, removing from kilo-rc1

[Sylvain Bauza (sylvain-bauza)]

As discussed during Nova meeting, attempt to merge it by RC1 as it would help the cells job to be green.

    Use cells.utils.ServiceProxy object within cells_api

    Now that all proxy objects are provided by cells.utils, we can directly use
    them instead of using a duplicate object.

Moving it to critical as it blocks the cells job to be green for Kilo

The patch needed to be merged is https://review.openstack.org/160506

[John Garbutt (johngarbutt)]

This can't be critical as it doesn't affect all users.

I am unsure about blocking the release on this bug, given we already warn people in the logs that cells is untested.

[John Garbutt (johngarbutt)]

Moving this out of RC1, its something we might want for RC2, to prove cells goes green in kilo-stable, but at this point, it seems unlikely to get merged.

    Fix how service objects are looked up for Cells

    When querying for services in the hypervisor API extension the queries
    need to be proxied through to the child cells.

    Note: We need to proxy the calls thru the HostAPI in order to have the
    same method for both non-cells and cells.
