Fix some message nits in the ZoneManager

[Joe Cropper]

This is a nit, but it was reported some of the options in the FC Zone Manager don't document their options as well as some inconsistent traces. This is used to track updates for these admittedly nit-level updates.

For example, the zone manager doesn't document acceptable zoning policies.

    Fix some message nits in the ZoneManager

    This patch addresses some nit comments I've received on some of the
    ZoneManager's conf options (e.g., not documenting the valid zoning
    strategies) and some other minor message format items.

    Cleaned up some globalization items as well (% => ,).

    Also fixed the UTs since they didn't work at all due to duplicate
    opt errors based on the UT structure.
