About the boto_profile setting that was abolished long ago

[nsano-rururu]

It is a setting called boto_profile that has been abolished for a long time, but if it is set, the implementation that outputs to the warning log remains. Can it be erased? .. If there is no problem, we will issue a PR.

elastalert.rst

``boto_profile``: Deprecated! Boto profile to use when signing requests to Amazon Elasticsearch Service, if you don't want to use the instance role keys.

util.py

    # Deprecated
    if 'boto_profile' in conf:
        elastalert_logger.warning('Found deprecated "boto_profile", use "profile" instead!')
        parsed_conf['profile'] = conf['boto_profile']

I agree, time to remove it.
