It is also possible to have mis-matched key file
while renaming directories.

Connection pausing added another exit condition in the listener
path, causing the bridge to leak connections instead of closing
them when signalled to close. Also adds some additional Close
paranoia.
Fixes#7823
Weaken TestV3ElectionObserve so it only checks that it observes a strictly
monotonically ascending leader transition sequence following the first
observed leader. First, the Observe will issue the leader channel before
getting a response for its first get; the election revision is only bound
after returning the channel. So, Observe can't be expected to always
return the leader at the time it was started. Second, Observe fetches
the current leader based on its create revision, but begins watching on its
ModRevision; this is important so that elections still work in case the
leader issues proclamations following a compaction that exceeds its
creation revision. So, Observe can't be expected to return the entire
proclamation sequence for a single leader.
Fixes#7749
This commit adds jwt token support in v3 auth API.
Remaining major ToDos:
- Currently token type isn't hidden from etcdserver. In the near
future the information should be completely invisible from
etcdserver package.
- Configurable expiration of token. Currently tokens can be valid
until keys are changed.
How to use:
1. generate keys for signing and verfying jwt tokens:
$ openssl genrsa -out app.rsa 1024
$ openssl rsa -in app.rsa -pubout > app.rsa.pub
2. add command line options to etcd like below:
--auth-token-type jwt \
--auth-jwt-pub-key app.rsa.pub --auth-jwt-priv-key app.rsa \
--auth-jwt-sign-method RS512
3. launch etcd cluster
Below is a performance comparison of serializable read w/ and w/o jwt
token. Every (3) etcd node is executed on a single machine. Signing
method is RS512 and key length is 1024 bit. As the results show, jwt
based token introduces a performance overhead but it would be
acceptable for a case that requires authentication.

The issue is caused by leader loss even after waitLeader() returns
which can happen if the test machine is flaky which triggers a leader loss
or the killed node is the leader since waitLeader() only scans followers in
TestRestartMember() and they can have the same older leader.
In those cases, clusterMustProgress() proceeds with no leader which triggers
the no leader error.
To get around that, use linearizable get in waitLeader() to ensure leader is up
and retries on kapi.create() in clusterMustProgress() to ensure it proceeds with
a leader.
