Docs improvement - readthedocs, sphinx and docs from code

[allburov]

For now, lib have many usefull API inside code, but have not any docs about it. All docs are manual created and separated from code To improvement docs, we need:

• [x] Convert all static MD to RST docs
• [x] Generate dynamic docs (through sphinx) and
• [x] Publish docs to readthedocs
• [x] Add more docstring with example to code

Good example jira-python. We need copy-paste and pull requests :)
