update portal with portal_number

portal_number moved to config. and passed through to dbconfig
storage was fine tuned to return portal_number in resultset for portal use (and future use as needed)
admin portal was adjusted to show portal number in (info, users)

connections, Stats and log works for current portal only. need to consider global view
