1caaa9ed4a test: test update for Go 1.12.5 and related changes 
Update to Go 1.12.5 testing. Remove deprecated unused and gosimple
pacakges, and mask staticcheck 1006. Also, fix unconvert errors related
to unnecessary type conversions and following staticcheck errors:
- remove redundant return statements
- use for range instead of for select
- use time.Since instead of time.Now().Sub
- omit comparison to bool constant
- replace T.Fatal and T.Fatalf in tests with T.Error and T.Fatalf respectively because the goroutine calls T.Fatal must be called in the same goroutine as the test
- fix error strings that should not be capitalized
- use sort.Strings(...) instead of sort.Sort(sort.StringSlice(...))
- use he status code of Canceled instead of grpc.ErrClientConnClosing which is deprecated
- use use status.Errorf instead of grpc.Errorf which is deprecated

2e95ace82b mvcc: fetch revisions with current revision, not 0, in HashByRev 
It was getting revisions with "atRev==0", which makes
"available" from "keep" method always empty since
"walk" on "keyIndex" only returns true.

"available" should be populated with all revisions to be
kept if the compaction happens with the given revision.
But, "available" was being empty when "kvindex.Keep(0)"
since it's always the case that "rev.main > atRev==0".

Fix https://github.com/coreos/etcd/issues/9022.

e9d096ae6b mvcc: don't allocate end revision while computing range 
Use 'nil' since it's only reading a single key. Also preallocates
the result slice based on limit / number of revisions fetched.

163fd2d76b mvcc: chunk reads for restoring 
Loading all keys at once would cause etcd to use twice as much
memory than it would need to serve the keys, causing RSS to spike on
boot. Instead, load the keys into the mvcc by chunk. Uses pipelining
for some concurrency.
