Complete task as SucceededWithIssues if there's at least one warning.

[tvardero]

Echo this command if eslint produced at least one warnings (not error, we already exit with non-zero):

echo "##vso[task.complete result=SucceededWithIssues;]"

This results in pipeline finishing not with "green check" label, but with "yellow exclamation mark".
