Ownership change for etcd-benchmark

Hi team,

Can you please change ownership of the etcd-benchmark charm from me to the account that owns Charmhub | Deploy Charmed PostgreSQL Watcher using Charmhub - The Open Operator Collection ?

Please add me as contributor, alongside @reneradoi @skourta and @medib

Also, please set the default track to 3.6

Thanks in advance!
