When settings stroke environment variables in job spec file, the values are passed to the executable surrounded by double quotes.

1. Set enviroment variable inside job spec file using interpolation:

   env { CONSUL_HTTP_ADDR = "${NOMAD_IP_app}:8500" }

2. enter shell inside container and do:

   echo $CONSUL_HTTP_ADDR

3. the result is surrounded with double quotes

   "10.0.2.15:8500"

while just 10.0.2.15:8500 is desired.
