Add erlang doctor

[chrzaszcz]

Add https://github.com/chrzaszcz/erlang_doctor for convenience, so we don't need to load it every time we use it.

Default trace table limits:

• 1000 for prod
• 100 000 for dev nodes.

After the number of collected traces reaches the limit, tracing is stopped, and the table doesn't grow anymore.

The recommended way to start the tool is tr:start(). Useful snippets will be added in a separate PR.
