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
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.
Adding integration test TestTransferLeadershipWithLearner, which ensures
that TransferLeadership does not timeout due to learner is automatically
picked by leader as transferee.
gRPC has moved the transport package to an internal-only directory. This
eliminates direct use of the transport package in the stress test in
favor of the error code from gRPC that represents a connection problem.
https://godoc.org/google.golang.org/grpc/internal/transport is the new
location for the package, which says it's not intended to be imported
directly. Instead, the maintainers suggested to use the code Unavailable
to detect a connection problem.
This change slightly reorganizes the stresser test error handling.
