[VOTE][LAZY] Move ECS, ORO and Regexp to Attic

This is a vote (or more correctly, three independent votes) to move
Jakarta ECS, Jakarta ORO and Jakarta Regexp to the Apache Attic, based
on the outcome of the most recent discussion on the topic.

Since none of these subprojects may have enough PMC members active,
this vote will be held by lazy consensus.

If you object, please also provide a reasonable explanation.

Vote runs for a week, ending no sooner than Aug 22nd, ~1:00 am Eastern
US. Vote is being held on general@jao but is being cross-posted to
ensure we reach the full audience. Please include general@jao in your
reply.
