[Feedhenry-raincatcher] Lerna-js based monorepo, lets try to migrate now before this dies again!

[Wojciech Trocki]

Thank you for contribution. Really good work - looking forward to use lerna.
I think that the biggest challenge with monorepo is to agree on how we
should support or possibly move out from our forking model.
Another challenge I see is just a building PR's.
Having code in one place is good start, but we would also need to fully
understand impact of that change to our customers that already forked
repositories etc.
It will be hard to revert that back in case of any problems.

I created travis configuration[1] for this. Let's check if we can build it
in some sensible time.
