cleanup of top-level dir

[ltalirz]

Some ideas for reducing files at the top level

• move conftest.py to tests
• remove bin/runaiida (is this needed?) Move to console_scripts in setup.json
• remove examples/ (@sphuber should these go to the docs?)
• remove utils/plugin_tpl (ok, that's not top-level but seems outdated)

* [ ]  move `conftest.py` to `tests`

Agreed - I think this should just work.

* [ ]  remove `bin/runaiida` (is this needed?)

I think this should remain. My current workflow doesn't use it much, but it is a convenient shorthand for script shebangs.

I agree, I would keep it. But maybe one could move it somewhere else? Or add it via the console_scripts?

I actually use the #!/usr/bin/env runaiida shebang a lot, so I would be in favor of keeping it. If it is indeed possible to install this through the console_scripts entry point instead, that would be an even better solution
