DAWN-151 ⁃ Node Startup Versioning Checks

[blockone-syncclient]

Is there any way to add code that checks the versions of the other nodes and logs stderr warnings if the releases do not match?

Or even a way to ask a node what version it's running?

If the node release versions do not match, that node should not start.

ATC:
Compile a diff version of eosd. Verify it will not connect to testnet.

Ideally we'd also have an overview tool that could query all nodes in a network and give an overview, like this:
https://ethstats.net/

Started node on local machine connecting to testnet (testnet is on STAT tag and local node is on master).

It shouldn't have gotten that far in the first place. Check output of eosd --version on both builds and verify they do not match.

Tested with tag 14 and does not work. Let me know if you need my config.ini.

Local config.ini used http port instead of net port. Works fine when we use net port.
