-----------------------------------
Hi [~sunilg]
I think the patch works as designed, thanks.
I've done some changes based on your patch, as following
# Added another end to end UT in \{{TestVolumeProcessor}} to verify the
container allocation with volumes
# Renamed to EXTERNAL_VOLUME_RESOURCE_TAG to represent tag name for csi
volumes in \{{ResourceUtils}}
# Modified the value of volume resource in
\{{testMultipleOpsForResourcesWithTags}} to avoid the possibility of
verification scenario slipping away
Please take a look, thanks

> The pre-provisioned volume is specified as a resource, but such resource is
> different comparing to what is managed now in YARN, e.g memory, vcores. They
> are constrained by 3rd party storage systems, so it looks more like an
> unmanaged resource. In such case, we need to ignore the resource calculation
> over them in the resource calculators. This can be done based on the resource
> tags.
