Add xhgui/xhprof UI support

[ptmkenny]

To debug PHP better, it would be awesome to have support for xhgui or the xhprof UI in the same way that we can add mailhog or phpmyadmin.

xhgui even supports docker out of the box so this might be an easy win.

There was a feature request to add xhprof support (closed due to going stale) is here: #148
