Pure Snapshot isolation would permit read conflicts. Change the name
from Snapshot to SerializableSnapshot to reflect that it will also
reject read conflicts.
etcd panic-ed, so defrag response just blocked for "days"
when the actual 'v3rpc' path never returned.
We should catch this earlier.

Getting gosimple suggestion while running test script, so this PR is for fixing gosimple S1019 check.
raft/node_test.go:456:40: should use make([]raftpb.Entry, 1) instead (S1019)
raft/node_test.go:457:49: should use make([]raftpb.Entry, 1) instead (S1019)
raft/node_test.go:458:43: should use make([]raftpb.Message, 1) instead (S1019)

Current benchmark doesn't have an option for configuring dial timeout
of gRPC. This commit adds --dial-timeout for the purpose. It is useful
for stopping long sticking benchmarks.
functional tester sometime experiences timeout during compaction phase. I changed the timeout calculation base on number of entries created and deleted.
FIX#6805
getting lease and keys info through raw rpcs rarely experience error such as EOF. This is considered as a failure and causes tester to clean up.
however, they are just transient problem with temporary connection issue which should not be considered as a testing failure. so we add retry logic in case of transient failure.
FIX#6754
The checkers and stressers should be composable without special cases; this
patch tries to address that while refactoring out some old cruft.
Namely,
* Single stresser/checker for a tester; built from composition
* Composite stresser via comma-separated list of stressers
* Split stressers into separate files
* Removed v2 only flags and special cases
* Rate limiter shared among key stresser and leases stresser
* Composite checker is now concurrent
* Stresser can return a Checker to check its invariants
* Each lease checker only operates on a single lease stresser
These really belong in tester code; the stressers and
checkers are higher order operations that are orchestrated
by the tester. They're not really cluster primitives.
