* [etcd] Update etcd 3.5.x to 3.6.5 - Add hashes for etcd 3.6.5 - Remove etcd v2 backup task for etcd 3.6 The etcd 3.6 removes 'etcdctl backup' command with ETCDCTL_API=2 - Downgrade etcd to 3.5 in netchecker The netchecker does not work with etcd 3.6 becaust it removes v2 API support (--enable-v2). And netchekcer does not support v3 API. * Fix: Change etcd config to clean up v2 store before upgrading etcd to 3.6 * Bump etcd to 3.6.8

# Disable --enable-v2 (recommended in 20289) and do workaround of 20231 (MAX_WALS=1 and SNAPSHOT_COUNT=1)
