Summary and body response output are interleaved when Hurl run multiple files

[jcamiel]

Running this command with Hurl 1.4.0 on macOS:

$ hurl hello.hurl assert_json.hurl
Hello World![
  { "id": 1, "name": "Bob"},
  { "id": 2, "name": "Bill"}
]

If we add --summary option:

Hello World![
  { "id": 1, "name": "Bob"},
  { "id": 2, "name": "Bill"}
--------------------------------------------------------------------------------
Executed:  2
Succeeded: 2 (100.0%)
Failed:    0 (0.0%)
Duration:  134ms
]

The last body response and summary seem to be interleaved.

They are not really interleaved, at least not in the same stream.
The body response is written to stdout while the summary is written to stderr.

$ hurl hello.hurl assert_json.hurl --summary >/dev/null
--------------------------------------------------------------------------------
Executed:  2
Succeeded: 2 (100.0%)
Failed:    0 (0.0%)
Duration:  64ms

$ hurl hello.hurl assert_json.hurl --summary 2>/dev/null
Hello World![
  { "id": 1, "name": "Bob"},
  { "id": 2, "name": "Bill"}
]

The summary should probably be another type of output.
meaning, it is written to stdout and instead of the body response,

We could have something like below

$ hurl hello.hurl assert_json.hurl --summary
Executed:  2
Succeeded: 2 (100.0%)
Failed:    0 (0.0%)
Duration:  64ms

or maybe with an option more explicit

$ hurl hello.hurl assert_json.hurl --output-type summary
Executed:  2
Succeeded: 2 (100.0%)
Failed:    0 (0.0%)
Duration:  64ms

Ha, I didn't think about stdout/sdterr !

Without any modification, we could improve the actual output with "flushing" the stdout before writing the summary to stderr ? (don't know if it will change something)

Summary is now a type of output (#351) and can not be used at the same time than the body response.
