automate releases

[jelhan]

This setups release-it and lerna-changelog to automate the release process. It also documents the required process in RELEASE.md.

Before doing the release the pull requests must be labeled correctly to be picked up by lerna-changelog.

This is based on rwjblue/create-rwjblue-release-it-setup. The first commit uses the current defaults. Second commits applies the changes proposed in rwjblue/create-rwjblue-release-it-setup#15.

It's splitted in two commits to ease review. Please squash on merging.

error semver@7.1.3: The engine "node" is incompatible with this module. Expected version ">=10". Got "8.17.0"

Seems like a dependency dropped node 8 support without doing a major release. 😞

release-it has already dropped node 8 support. Will rebase after #308 is merged.

Cool tooling. Looks good to me 👀

I have gone through the PRs since the last version and tried to label them. Probably worth double-checking the labels I have used are correct.

Rebased after #308 has been merged. Tests should pass now.

You motivated me to do the same for the other PRs and update the changelog which was very outdated. This also includes a nice example of how the generated changelog looks like into this pull request.

I think this branch needs a rebase.

Love the new changelog ❤️

[jelhan]

Rebased.

Sorry for not reviewing but it seems that you both are doing an amazing job! @jelhan and @gilest
Awesome work!
