Bug is in api method deregister service.

[linuxoid69]

import consulate

consul_host = os.environ['CONSUL_HOST']

consul = consulate.Consul(consul_host)

consul.agent.service.deregister('redis')

Your code use Method GET. You need to use ### PUT.
So, service can't been deleted.

I'm seeing this as well. Is this the wrong API to call?

This seems related to the following change in Consul: hashicorp/consul#3659 (comment)

[Deadkorskiy]

pip was not updated https://pypi.org/project/consulate/#files
consul.agent.service.deregister('redis') still use return self._get_no_response_body(['deregister', service_id]) instead _put_no_response_body().
