Max length userData

[andrejvanderzee]

Hi there,

I am encountering this issue when using ignition_file when copying encrypted PKI assets.

Error: Error applying plan:

1 error(s) occurred:

• module.kubernetes.module.masters.aws_launch_configuration.master_conf: 1 error(s) occurred:

• aws_launch_configuration.master_conf: Error creating launch configuration: ValidationError: 1 validation error detected: Value 'XXXXXXXXX' at 'userData' failed to satisfy constraint: Member must have length less than or equal to 21847
  status code: 400, request id: 82919b36-bd60-11e7-8156-e1805ec22de2

This is one of the failing configs:
