Elastic support for aio-cassandra

[Riki-1mg]

Is your feature request related to a problem? Please describe. I am using aio-cassandra in my asyncio based application. Now that I have integrated my app with the aio-cassandra library I don't see the logs instrumentation for it.

Describe the solution you'd like Similar to aiopg and asyncpg, there should be instrumentation for aio-cassandra as well

Describe alternatives you've considered N/A

Additional context async libraries are getting much popularity and these should be added for a popular apm solution like elastic. aio-cassandra: https://github.com/CharAct3/aiocqlengine
