Do not poll counters in bulk mode during initialization for objects that support bulk per CLI option

Do not poll counters in bulk mode during initialization for objects that support bulk per CLI option

1. Read the counter groups that support bulk mode from CONFIG_DB.DEVICE_METADATA|localhost.supporting_bulk_counter_groups
2. Generate CLI options to syncd
3. Based on CLI options syncd records the counter groups that support bulk mode. For those objects, we do not need to poll them in bulk mode during initialization

@kcudnik I added UT to meet coverage.

UT failed due to a conflict with another PR. Fixing.
