etcdctl/ctlv3: migrate cheggaaa/pb.v1 to cheggaaa/pb/v3
This commit also changes the format of the progress bar, from using a
custom progress bar to the default provided by the library.
Old behaviour:
./benchmarkv1 put
0 / 10000 B ! 0.00%
3987 / 10000 Boooooooooooooom ! 39.87%
10000 / 10000 Boooooooooooooooooooooooooooooooooooooooooooo! 100.00% 1s
New behaviour:
./benchmark put
6536 / 10000 [----------------------->________________] 65.36% 7053 p/s
10000 / 10000 [---------------------------------------] 100.00% 7581 p/s

This change makes the etcd package compatible with the existing Go
ecosystem for module versioning.
Used this tool to update package imports:

The benchmark as a sub command of put when provided will fetch hashkv and checks
the time taken to get it.
Fixed # 8910
Provider a way to etcd user to check how long it takes to get
hashkv in user enviornment. The command ouput will provide time taken
to get hashkv along with db file size.
Reports depended on writing all results to a large buffered channel and
reading from that synchronously. Similarly, requests were buffered the
same way which can take significant memory on big request strings. Instead,
have reports stream in results as they're produced then print when the
results channel closes.
