version command

[dexhorthy]

We need a command like ship version https://github.com/replicatedhq/ship that outputs the tag and git info.

@laverya This appears to have been added in #54 and #52 , but requires an API token to check the version:

$ replicated version  
Error: Please provide your API token

Usage:
  replicated version [flags]

Flags:
    -h, --help   help for version

Global Flags:
        --app string     The app slug or app id to use in all calls
      --token string   The API token to use to access your app in the Vendor API

Please provide your API token

This seems to work without an API token for me now. At least I tried by unsetting my REPLICATED_* environment variables ard ran replicated version.
