Trigger new Travis build on new HA version available

[pinkywafer]

Travis builds are normally triggered by commits/pr to the repo. When a new Home Assistant version becomes available, trigger a Travis build against the new version of home Assistant. This will validate config automatically before the new version is installed.

Trigger build using Travis rest API: https://docs.travis-ci.com/user/triggering-builds/

• Add build status to update notifications, so that build status is evident before installation

rest command to trigger build:

rest_command:
  travis_build:
    url: https://api.travis-ci.org/repo/pinkywafer%2FHome-Assistant_Config/requests
    method: POST
    headers:
      authorization: !secret travis_api_key
      Content-Type: "application/json"
      Accept: "application/json"
      Travis-API-Version: 3
    payload: '{"request": {"branch":"master"}}'

This will be pretty neat if you can Test the new build of HA against your COnfig and then drop a PASS/FAIL comment on the ISSUE that tracks the new HA upgrade task.

@CCOSTAN working!! Note that if you do this, the secret for Travis API has to be "token YourApiKey" and the github issue api key also has to have token before the api key... took me ages to figure that out!!
