[doc] update requirements for all consul modules/lookups (#10863)

* [doc] update requirements for consul_kv module

python-consul has been unmaintained for a while. It uses a legacy way of passing the Consul token when sending requests. This leads to warning messages in Consul log, and will eventually break communication. Using the maintained py-consul library ensures compatibility to newer Consul versions.

* [doc] replace all python-consul occurrences with py-consul

* [fix] tests and possible pip server errors

* [chore] remove referencce to python-consul in comment
