* [flex-counters] Delay flex counters stats init for faster boot time (sonic-net#1749)

Signed-off-by: Ying Xie <ying.xie@microsoft.com>

Why I did it
There is a regression on 2700 platform where the evidence points to the flex counter change.

How I did it
Back track the swss submodule head to exclude:

**What I did**
Update flex counters DB with counters stats only when counters are enabled.
As long as the polling counters are not enabled, flex counters information will stored internally on PortsOrch.

**Why I did it**
Creating flex counters objects on the DB will trigger 'SYNCD' to access the HW for query statistics capabilities.
This HW access takes time and will be better to finish boot before doing this (mainly for fast-reboot but good to have in general).
The flex counters are not crucial at boot time, we can delay it to the end of the boot process.

**How I verified it**
Reboot a switch and observer the flex counters DB populated after counters are enabled.
