[devstack plugin]cells1 conductor config file isn't modified by the plugin

[Matt Simonin]

It seems that devstack now deploys a cell0 and a cell1, each running one conductor.
The osprofiler plugin runs in the post-config phase to add the profiler section and the corresponding values in the NOVA_CONF file. The conductor of cell0 is well configured but the conductor of the cell1 miss the profiler section in its configuration.

My (partial) understanding so far is that the configuration of the cells1's conductor is build from scratch[1] and not derived from a the base nova.conf[2]. The osprofiler devstack plugin only modify the base nova.conf file.

Cell conductor is executed with its own config file (/usr/bin/python /usr/bin/nova-conductor --config-file /etc/nova/nova_cell1.conf), but currently this file is not in a list in osprofiler's Devstack plugin (https://github.com/openstack/osprofiler/blob/master/devstack/lib/osprofiler#L14-L29)

    Initialize osprofiler in Nova Cell configs

    Nova Cell conductor has its own config file and Devstack plugin
    should update it when osprofiler is enabled.
