CORD-1583 Bug fixes for dual ToRs
Two things:
- In dual (paired) ToR scenarios it is possible to have the same outport
in multiple buckets in a hash group, as long as they have different labels.
When adding buckets this was taken into account. But when removing buckets,
only outport was being checked. This bug fix ensures that labels are checked
as well when removing buckets.
- In dual ToR scenarios, getting the right set of hash buckets proved difficult
with existing 'retryHash' mechanism. Repealed and replaced with a bucket corrector
mechanism that periodically corrects the hash group buckets when the topology
has been stable for the last 10 secs. Required the introduction of a VERIFY
operation in Next Objectives. Also added a cli command to trigger this
operation manually.
