TryLock locks the mutex if not already locked by another session.
If lock is held by another session, return immediately after attempting necessary cleanup
Added integration test
Fixes#10493
Overwrite authority when it's IP.
When user dials with "grpc.WithDialer", "grpc.DialContext" "cc.parsedTarget"
update only happens once. This is problematic, because when TLS is enabled,
retries happen through "grpc.WithDialer" with static "cc.parsedTarget" from
the initial dial call.
If the server authenticates by IP addresses, we want to set a new endpoint as
a new authority. Otherwise
"transport: authentication handshake failed: x509: certificate is valid for 127.0.0.1, 192.168.121.180, not 192.168.223.156"
when the new dial target is "192.168.121.180" whose certificate host name is also "192.168.121.180"
but client tries to authenticate with previously set "cc.parsedTarget" field "192.168.223.156"

Description: w.mu is locked at line 385 and unlocked at line 396. Among 5 return statements in this function, 4 are below line 396 but there is 1 return at line 387.
Fix: Add w.mu.Unlock() before that return at line 387.
Update to Go 1.12.5 testing. Remove deprecated unused and gosimple
pacakges, and mask staticcheck 1006. Also, fix unconvert errors related
to unnecessary type conversions and following staticcheck errors:
- remove redundant return statements
- use for range instead of for select
- use time.Since instead of time.Now().Sub
- omit comparison to bool constant
- replace T.Fatal and T.Fatalf in tests with T.Error and T.Fatalf respectively because the goroutine calls T.Fatal must be called in the same goroutine as the test
- fix error strings that should not be capitalized
- use sort.Strings(...) instead of sort.Sort(sort.StringSlice(...))
- use he status code of Canceled instead of grpc.ErrClientConnClosing which is deprecated
- use use status.Errorf instead of grpc.Errorf which is deprecated

This commit adds a feature for creating a user without password. The
purpose of the feature is reducing attack surface by configuring bad
passwords (CN based auth will be allowed for the user).
The feature can be used with `--no-password` of `etcdctl user add`
command.

Update TestMemberPromote to include both learner not-ready and learner
ready test cases.
Removed unit test TestPromoteMember, it requires underlying raft node to
be started and running. The member promote is covered by the integration
test.
