Currenly Member exports GrpcURL already as a struct variable. However,
when addressing the var-naming linting issues, renaming it from GrpcURL
to GRPCURL, clashes with the GRPCURL() function.
Given that it's already an exported variable, there's no need to define
a getter function. The use of this variable is also mixed, with calls to
both the exported variable (GrpcURL) and the function [GRPCURL()].

Unlike SnapshotWithVersion, the client.Snapshot doesn't wait for first
response. The server could open db after we close connection or shutdown
the server. We can read few bytes to ensure server opens boltdb.

Changed TraceKey/StartTimeKey/TokenFieldNameGRPCKey to struct{} to
follow the correct usage of context. Similar patch to #8901.

fix the unexpected blocking when using Barrier.Wait(), e.g.
NewBarrier(client, "a").Wait() will block if key "a" is not existed but "a0" is existed, but it should return immediately.

The TestLeasingDeleteRangeContendTxn is trying to test for RangeDelete when
the target resources are being updated. When the `txnLeasing` wants a
server-side transaction, it needs to ensure all the keys mod revision should
be leass than what it saw. If the compare fails, it will repeat to apply the
server-side transaction until it is sucessful. I believe the test-case is
trying to verify how the `txnLeasing` handles the race issue.
Before the patch #15401, the resource-updating goroutine keeps updating until
the RangeDelete finishes. The testcase is flaky because two goroutines are
sharing one `ctx` and grpc-go client won't wait for the response if `ctx`
has been canceled.
For example,
| DelLease Goroutine | PutLease Goroutine | ETCD Server | Key/0 Status |
| -- | --- | -- | -- |
| deleted | | | version = 0 |
| | send update(key/0=123) req | received update(key/0=123) req | version = 0 |
| cancel | | | version = 0 |
| | exit because of cancel | | version = 0 |
| get key/0 by putkv | | | version = 0 |
| | | applied update(key/0=123) | version = 1 |
| get key/0 by raw-cli | | | version = 1 |
So `raw-cli` gets `[key/0=123]` while the `putkv` gets `[]`. If `putkv`
applies two update reqs to ETCD server and the last one is canceled
before apply, the error will be like:
```
expected [key:"key/0" version:2 value:"123" ], got [key:"key/0" version:1 value:"123" ]
```
The resource-updating goroutine should not share the ctx with RangeDelete here.
And I also revert current main branch because the resource-update goroutine
only updates 8 times and might exit before `RangeDelete`. In this case,
the `txnLeasing` is not handling the race issue.

Fixes etcd-io#15352.
Depending on the goroutine scheduling, the expected count of 8 might not
have been reached yet. This ensures the routine won't stop earlier than
that.
