Update README.md to link to the open issue that shows Ansible 2.8.x doesn't work with Kubespray.  The requirements.txt file is already fixed to 2.7.8 so only the README needed updating, I think.

Long option --become was used in the example but in the comment describing it the short option -b was used.
Use same option in description and example to avoid confusion.
