Upgrade MCP to Fedora 26

[Jared-Sprague]

Need to upgrade the mcp hosts to fedora 26 and ansible'ize it. Here are the things it currently does:

• [x] RPM repo for builds

• [x] Sync's zorbio_version git repo

• [x] Runs the ansible playbook that deploys new builds to zor nodes

• [x] Host where new zor nodes are provisioned from using ansible playbook for ssh key security

• [x] Monitors NodeBalancers for load and sends notifications if there is a need to add more nodes

• [x] In order to push builds to MCP you need to have you ssh public key installed on it.

I'm going to be taking detailed notes so I don't forget how this is setup again.

First linking the architecture diagram for reference: https://github.com/Jared-Sprague/zorbio/issues/320

Need to answer this question: When creating new linode nodes, how is the root ssh key copied over?

[Jared-Sprague]

The ssh key that gets installed when a new linode is created is defined in the .linodecli/config file. Here is the output from linode configure:

Path to an SSH public key to install when deploying a new Linode. (Optional)
