We shouldn't fail the grpc-server (completely) by a not implemented RPC.
Failing whole server by remote request is anti-pattern and security
risk.

The first bug fix is to resolve the race condition between goroutine
and channel on the same leases to be revoked. It's a classic mistake
in using Golang channel + goroutine. Please refer to
https://go.dev/doc/effective_go#channels
The second bug fix is to resolve the issue that etcd lessor may
continue to schedule checkpoint after stepping down the leader role.

Items resolved:
1. fix the vet error: possible misuse of reflect.SliceHeader;
2. fix the vet error: call to (*T).Fatal from a non-test goroutine;
3. bump package golang.org/x/crypto, net and sys;
4. bump boltdb from 1.3.3 to 1.3.6;
5. remove the vendor directory;
6. remove go 1.12.17 and 1.15.15, add go 1.16.15 into pipeline;
7. bump go version to 1.16 in go.mod;
8. fix the issue: compile: version go1.16.15 does not match go tool version go1.17.11,
refer to https://github.com/actions/setup-go/issues/107;
9. fix data race on compactMainRev and watcherGauge;
10. fix test failure for TestLeasingTxnOwnerGet in cluster_proxy mode.

- retry_interceptor_test causes:
clientv3/naming/grpc.go:25:2: module google.golang.org/grpc@latest found (v1.46.0),
but does not contain package google.golang.org/grpc/naming
https://github.com/etcd-io/etcd/issues/12124
To fix a bug in the retry logic caused when the auth token is cleared after receiving `ErrInvalidAuthToken` from the server and the subsequent call to `getToken` also fails due to some reason (eg. context deadline exceeded).
This leaves the client without a token and the retry will continue to fail with `ErrUserEmpty` unless the token is refreshed.
Problem: Defrag was implemented before custom bolt options were added.
Currently defrag doesn't restore backend options.
For example BackendFreelistType will be unset after defrag.
Solution: save bolt db options and use them in defrag.
Update go to 1.15.15 which is the latest of 1.15 because linux-amd64-fmt fails with go 1.15.13.

github.com/dgrijalva/jwt-go has CVE https://github.com/advisories/GHSA-w73w-5m7g-f7qc
and is already archived. etcd v3.4 should use a community maintained fork
github.com/golang-jwt/jwt which provides the fixed version of the CVE.

Ensure the client which access etcd via grpc-gateway won't
be limited by the MaxCallRecvMsgSize. Here we choose the same
default value of etcdcli as grpc-gateway's MaxCallRecvMsgSize.
