MDS config transactions timeout/first latency are very high

After Taking GOCBC-1028

MDS config:
Host1: query service (no data service)
Host2: data, index

begin work;
select * from `travel-sample` limit 1;

First time when we open new bucket we call CreateAgent()
ConnectTimeout: 10000 * time.Millisecond,
KVConnectTimeout: 7000 * time.Millisecond,

Which returns immediately.
When called read it timeout in 2.5sec.

This almost makes new bucket (dropped/recreated) involves in transaction those most likely timeout because warmup can take quite time.

If we start wait until Warmup latency can go up particularly insert statements we don't write until commit.
If we don't wait reads are failing.

What will be recommendation from gocbcore. If wait warm up is option what will be time recommended.
