* Moved flot in ui-shared-deps and leavt only one version. * Removed unneeded import * use commonJS so we can execute code between loading specific modules * prefix i18n keys with flot. * Fix Internationalization * remove duplicate pie plugin Co-authored-by: spalger <spalger@users.noreply.github.com> Co-authored-by: Kibana Machine <42973632+kibanamachine@users.noreply.github.com>
