Description (partial)

Keepalive configuration fails with error "BFD session running,cant enable keepalive"" even though BFD configuration is removed before configuring keepalive

This defect occurs if bfd multiplier or bfd minimum-interval is removed and then keepalive is configured.

Following scenarios cause this problem:

1. When either bfd multiplier or bfd minimum-interval is removed with bfd destination in same commit. Subsequent keepalive configuration would fail
2. When bfd destination is removed first, then bfd multiplier or bfd mininum-interval is removed, then subsequent keepalive configuration would fail.
3. Either bfd multiplier or bfd minimum-interval or both is configured, then removed. Subsequent keepalive config would fail.
