fastest way to check if backup

[Yakov Zhdanov <yz...@apache.org>]

Guys,

cctx.affinity().backups(entry.key(),
cctx.topology().topologyVersion()).contains(cctx.localNode())

does not seem to be fast enough.

cctx.affinity().backups() returns F.view() over ArrayList with excluded
first element which always ends up into an iteration.

Alex G, thoughts?

I do not see how we can avoid iteration in a general case because cache can
have more than one backup. But I think it makes sense to create a separate
method which will not use views and will start iteration from the second
element of nodes collection (which is always an ArrayList).
