`lerna bootstrap` should support --only-updated flag

See original GitHub issue

Expected Behavior

lerna bootstrap should respect the new --only-updated flag for CI purposes. lerna bootstrap --only-updated should only symlink packages that have updates, and install the others as external dependencies.

Current Behavior

lerna bootstrap does not respect the new --only-updated flag

Possible Solution

Like I mentioned above, update lerna bootstrap to respect the --only-updated flag and only symlink modules if they’ve been updated. Otherwise, install them as external dependencies.

Context

We would love to run our build/test/lint on only updated packages as this would speed up our CI builds significantly. Since as of today lerna bootstrap does not respect the new --only-updated flag, when we run lerna exec --only-updated -- yarn build it only builds out updated packages (yay). However; when we run lerna exec --only-updated -- yarn test now, tests that depend on modules that did not change fail because they were not built (boo). So currently, we can only get away with building all packages and running lint/test on only updated packages.

Sounds like @treshugart is on the right track. I wasn’t sure what the best way to implement it was, I just know the use case we have, and it’s the same as his.
