Replace all etcd versions with the centralized definitions
...
We have already defined all the constant etcd versions in the
centralized place api/version/version.go. So we should replace all
the versions with the centralized definitions.

Returning nil means that raft.Trigger was not called, causing member to
wait infinitly for response for response on raft request.

server: Depend only on cluster version to detect downgrade
...
Problem with old code was that during downgrade only members with
downgrade target version were allowed to join. This is unrealistic as
it doesn't handle any members to disconnect/rejoin.

server: Implement storage schema migration to follow cluster version change and panic if unknown storage version is found
...
Storage version should follow cluster version. During upgrades this
should be immidiate as storage version can be always upgraded as storage
is backward compatible. During downgrades it will be delayed and will
require time for incompatible changes to be snapshotted.
As storage version change can happen long after cluster is running, we
need to add a step during bootstrap to validate if loaded data can be
understood by migrator.
