feat(@schematics/angular): update karma to v3.0

[sibiraj-s]

Update Karma to v3.0.0 which resolves several vulnerable dependencies

[clydin]

This will need to be a feat since it changes the generated project.

[sibiraj-s]

@clydin updated the change.

[clydin]

One more quick change: the scope for the commit message should be “@schematics/angular”

[sarunint]

@sibiraj-s please also mention "Close #10963" in the commit message so that the issue is automatically closed when the PR is merged.

[sibiraj-s]

@clydin . Updated the commit scope.

Since one of two issues in #10963 is already addressed. This Commit will close the issue

@sibiraj-s Additional (sorry for just piling on); could you also change the version in the root package.json? It will be installed for our tests.

[sibiraj-s]

@hansl. Also karma-cli is redundant. Is it okay to remove that to?

[hansl]

Then please do :) . We don't use the CLI, not sure why it's there.

[sibiraj-s]

Done.

This should also fix the timeout issues while testing in CI

[hansl]

Looks good. Seems like your change might have some merging issue. Rebase and we'll merge it in as soon as caretaker is around (Monday at the latest).
