Persistent data should be configured in agent side.
There is no need to specify the data-dir in tester side.

election runner can deadlock in atomic release().
suppose election runner has two clients A and B.
if A is a leader and B is a follower, B obtains lock
for release() and waits for A to close(nextc) which signal
next round is ready. However, A can only close(nextc) if it
obtains lock for release(); hence deadlock.
this pr removes atomicity of validate() and release() in global.go
and gives the responsibility of locking to each runner.
FIXES#7891
etcd tester runs etcd runner as a separate binary.
it signals sigstop to the runner when tester wants to stop stressing.
it signals sigcont to the runner when tester wants to start stressing.
when tester needs to clean up, it signals sigint to runner.
FIXES#7026
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)

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
