External Turn server configuration for BBB 2.6

[M P]

This one stumped me for a few days until I figured out that configuration files have been moved in 2.6.  The documentation regarding turn servers has not yet been updated, but you may follow that guide so long as you note the following crucial detail:

In the section titled "Configure BigBlueButton to use your TURN server", you should note that the location of turn-stun-servers.xml no longer resides in /usr/share/bbb-web/WEB-INF/classes/spring.  There is still a file there, but as per the note in resources.xml:

 "moved the following import statement for turn-stun-servers.xml to resources.groovy"

resources.groovy has the following line:

def turnConfigFilePath = "/etc/bigbluebutton/turn-stun-servers.xml"

In short, make your changes to /etc/bigbluebutton/turn-stun-servers.xml instead if you wish to use an external turn/stun server.

I hope this helps someone!
