update wildfly-mysql-javaee7 with bridge networking to work with docker-compose 2 format and be compatible with recent versions of docker

[quentinburley]

the example here:
wildfly-mysql-javaee7/docker-compose.yml

relies on:
docker-compose --x-networking up -d

which works well in: docker-compose version 1.5.2, build 7240ff3

but in current versions of docker-compose (since docker-compose 1.6) the --x-networking option has been deprecated in favour of docker-compose.yml in version:2 format.

I would be very interested to see a similar example to 'wildfly-mysql-javaee7' but working with a recent version of docker-compose and possibile in the version:2 format.

Thanks.

https://github.com/arun-gupta/docker-images/blob/master/wildfly-couchbase-javaee7/docker-compose.yml is already updated to version 2. Will update the instructions.
