5f8cd5bd39 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.

1ea53d527e server: Save consistency index and term to backend even when they decrease 
Reason to store CI and term in backend was to make db fully independent
snapshot, it was never meant to interfere with apply logic. Skip of CI
was introduced for v2->v3 migration where we wanted to prevent it from
decreasing when replaying wal in
https://github.com/etcd-io/etcd/pull/5391. By mistake it was added to
apply flow during refactor in
https://github.com/etcd-io/etcd/pull/12855#commitcomment-70713670.

Consistency index and term should only be negotiated and used by raft to make
decisions. Their values should only driven by raft state machine and
backend should only be responsible for storing them.

bfd5170f66 add a txPostLockHook into the backend 
Previously the SetConsistentIndex() is called during the apply workflow,
but it's outside the db transaction. If a commit happens between SetConsistentIndex
and the following apply workflow, and etcd crashes for whatever reason right
after the commit, then etcd commits an incomplete transaction to db.
Eventually etcd runs into the data inconsistency issue.

In this commit, we move the SetConsistentIndex into a txPostLockHook, so
it will be executed inside the transaction lock.

ff3729c4d5 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.
