Reload env components page after deployment of empty environment

This patch adds javascript that reloads the page with environment
components until deployment of empty environment is finished. It
allows to add new components to the page without manual page refresh.
Reload is made with timeout set in horizon config
'ajax_poll_interval'. Currently there is no other way to detect the
moment of empty env deployment finish.
