* remove s390x support

* Add basic RPC metrics via `mc support top rpc` (minio#5060)

Example:
```
λ mc support top rpc myminio
      SERVER            CONCTD  PING    OUT Q   RECONNS STR IN  STR OUT MSG IN  MSG OUT
 To  127.0.0.1:9001       5     0.5ms     0        0    -> 20    0 ->   60007    60089

From 127.0.0.1:9005       5     0.5ms     0        0     -> 4    0 ->   33136    33515
 To  127.0.0.1:9006       5     0.0ms     0        0     -> 0    4 ->   33627    33161
From 127.0.0.1:9006       5     0.0ms     0        0     -> 4    0 ->   33162    33627
```

There is already server support for metrics.

* Report errors and better file names for mc support inspect  (minio#5062)

Check the returned stream for errors and show them. Don't upload/keep pointless data

Use the request alias to create a better file name...

Example:

```
λ mc support inspect play/testbucket/testdat/**
mc: <ERROR> Unable to download file data. GetRawData: No files matched the given pattern.
```

Previously the error would just be ignored.

```
λ mc support inspect --airgap play/testbucket/testdata/**
File data successfully downloaded as inspect-play_testbucket_testdata.enc
```

Previously all files would be called `inspect-data.enc`, which would just be difficult to distinguish.

* Add support rpc JSON replay. (minio#5064)

Add realtime replay of captured JSON data.

Example:
```
λ mc support top rpc --json myminio >rpc.json

λ mc support top rpc -in=rpc.json
```

* Add string/json output string mc pipe (minio#5065)

This commit adds a string message and json output to mc pipe.  The
implementation is heavily inspired by the one in mc cp, just adapted to
the different semantics of pipe.

* Mark batch job status properly (minio#5066)

Client side overall status was always shown as `in-progress` even if
job was successful or failed.

* Only warn if less than 28 days to cert expires (minio#5077)

Fixes minio#5076 as much as reasonable.

* lint: Fix new detected lint complaints (minio#5080)

* heal: Simplify bucket healing status (minio#5079)

Avoid using the drive count concept to pick a color for a bucket healing
result. This was straightforward when we were healing a bucket per erasure 
set, but now it becomes more complex to show a result.

Pick green if everything is okay, yellow if a bucket is missing in a
drive, red for any other drive state (unformatted, offline, ..), and
grey for any weird situation.
