Publish an initial v1.0.0 with conventional commits

[m-mayank]

Considering with the recent changes, now lerna publish does not entertains Breaking Change when a given package is in 0.x.x state. The feature is quite useful, but with this I could not found a way to have a Initial release for a given package in an automated CI ecosystem.

Also the same becomes a problem when we are in monorepo having multiple packages, and then when we want to add a new package.

The only option i could find as of now is to commit a package with v1.0.0 and the lerna publish releases it as v1.0.1

Executable	Version
lerna --version	v3.22.1
npm --version	v6.12.0
node --version	v12.13.0

Note: the same issue was highlighted in #2325, but has no answer yet and the issue seems to be closed

I'm not sure how to go from 0.x.x to x.x.x in CI, but locally it can be done by:

1. Change the version in package.json for the packages to publish from 0.x.x to 1.0.0-1 as per this comment
2. Graduate them to a release with lerna version --conventional-graduate my-package,my-other-package (will create release notes etc on GitHub)
3. Finally publish them to npm with lerna publish from-package
