Revert "MB-24055: Change default ep-engine ht_size from 3079 to 0"

Issues seen in rebalance performance - see 
https://issues.couchbase.com/browse/MB-24107. Suspect the initial
HashTable sizes (and the fact that we only run the HashTable resizer
every 60s). Reverting this patch while further investigation continues.

This reverts commit 07b7280.
