Support for RHEL7

[elosoman]

I've been using MUPX for a while. What a life saver this has been. My current environment standardized on RHEL7 and there where some problems that needed to be ironed out on the platform.

These changes allow MUPX to work on RHEL7.

I've been able to get mupx setup, deploy and logs tested. These operations run without error but i'm finding a problem when running the meteord image with the deployed app. docker ps shows both mongodb and the app image, but it can not be connected to on the network (locally on the server or remotely)
telnet 192.168.117.51 80
Trying 192.168.117.51...
Connected to 192.168.117.51.
Escape character is '^]'.
Connection closed by foreign host.

This may be an issue with docker network that i'm still verifying. Not sure if anybody has any suggestions on this? Still investigating.

Ok ... so the networking issues that I was experiencing where due to our internal proxy server. I was able to resolve them by setting http_proxy to the mupx.json for this environment. There are no issues with any mupx operation on a RHEL7 server. I do not have ability to test CentOS.

Is there any interest in merging RHEL support?
