This commit adds a Jeager exporter for OpenTelemetry.  This exporter is based
on https://github.com/census-instrumentation/opencensus-python/tree/master/contrib/opencensus-ext-jaeger.

The exporter uses thrift and can be configured to send data to the agent and
also to a remote collector.

- use Args: notation in documentation
- remove license boilerplate from empty file
- use "not x" instead of "len(x) == 0"
- rename logger

deque.copy() was introduced in python3.5, this commit removes it's usage and
replaces it for deque(another_deque).

use deque(dq) instead of deque.copy()

order of some data structures was causing random fails.

- remove "optional" from docs
- fix some type annotations
- make pylint check the code
- fix pylint issues

there is a long discussion ongoing yet about how to include generated files
in the repo, so for now just put them here.

were are not checking annotations with mypy, so remove types annotation completely
