Center modals and fix sizing

Previously the modals were not centered on the screen and the size
of the modal was set to 50% of the screen, leading to a lot of white
space within modals with less content. This sizes the modal based on
the amount of content within and centers the modal. Also adds the grey
modal overlay to the 'confirm network settings' modal to be consistent
with the other pages.

Resolves openbmc/phosphor-webui#35

Tested: Viewed all modals currently in GUI (Firmware page, network page,
        and overview page) and modals were sized correctly and appeared
        with the modal overlay in the background.
