Add Reboot BMC page

Created a ControlStore with the intention to consolidate actions
across multiple subnav pages under the 'Control' tab, instead of
creating a dedicated RebootBmc store with one action.

- Update PageSection component to make sectionTitle prop optional
- Changed PageTitle computed property to data since the value
  doesn't change during the component lifecycle
- Change PageSection <section> element to <div> to avoid
  accessibility issues
