removed cookieSyncDelay from config

Removed cookieSyncDelay from config since we have more configuration options now with the userSync object.

Documents prebid/Prebid.js#3061.

Actually I think this should be handled in a different way -- we should add a deprecation notice right now, and not actually remove it until 2.0.

thanks for this @thewizarodofoz -- but since we can't merge it until 2.0 -- API change, I think we want to add the deprecation now and remove it later.

Yes I thought a deprecation notice is more suitable, but then I saw that cookieSyncDelay is actually not being used anywhere in the master branch (except for in the config object itself).

The user sync module is using the new syncDelay param. So unless I am missing something, I think leaving cookieSyncDelay is actually misleading.

Ok.
