Ability to opt of of using `npm ci`

Expected Behavior

Being able to tell lerna bootstrap to explicitly use npm install instead of npm ci

Current Behavior

Since 3.0.0-beta.15, lerna bootstrap uses npm ci if it’s a version of npm that supports it and you pass the --ci flag. However, on CI environments the --ci flag is always true, and there’s no way to turn it off without messing around with environment variables, which would have other side effects.

Context

Since we’re not committing package-lock.json files (our current tooling doesn’t play nicely with them at present) npm ci errors, and we can’t currently use lerna on CI with npm@5.7.

lerna bootstrap --no-ci doesn’t work?
