remove deprecated role variable

[fuzzygroup]

Hi,

The version variable no longer works. Here is a pull request where it is removed. Thank you for the role.

With Ansible version 2.2, and possibly earlier you will see an error like

ERROR! 'version' is not a valid attribute for a RoleMetadata

The error appears to have been in '/usr/local/etc/ansible/roles/crushlovely-sidekiq-2.1.0/meta/main.yml': line 2, column 1, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

---
galaxy_info:
^ here

Ansible failed to complete successfully. Any error output should be
visible above. Please fix these errors and try again.
