"collie: command not found" when using default known_stores

[Xingchao Yu]

In glance-api.conf, when we using known_stores's default value:

known_stores = glance.store.filesystem.Store,
               glance.store.http.Store,
               glance.store.rbd.Store,
               glance.store.s3.Store,
               glance.store.swift.Store,
               glance.store.sheepdog.Store,
               glance.store.cinder.Store,

If we just use file or rbd or other backend except sheepdog, when starting glance-api service , we would see the glance-api log throw errors something like:

2013-12-01 04:11:36.501 20725 INFO glance.store.filesystem [-] Directory to write image files does not exist (/var/lib/glance/images/). Creating.

2013-12-01 04:11:36.554 20725 ERROR glance.store.sheepdog [-] Error in store configuration: Unexpected error while running command.

Command: collie

Exit code: 127

Stdout: ''

Stderr: '/bin/sh: collie: command not found\n'

2013-12-01 04:11:36.685 20725 WARNING glance.store.base [-] Failed to configure store correctly: Store cinder could not be configured correctly. Reason: Cinder storage requires a context. Disabling add method.

So the only way to avoid this is to configure your own known_stores right, for example: if you don't use sheepdog, just remove it from the known_stores.

    Add known_stores option in class glance::api

    In glance-api, if you use known_stores's default value and didn't use
    all of the stores listed in known_stores, then glance-api service will
    throw an error to point out which store missing, see more description
    in related bug link.
    This patchset adds known_stores option in glance::api, so that users
    can configure it by their own needs.
