[Bug 1785821] Re: "pastebinit -i file" to paste.openstack.org fails: Object of type 'bytes' is not JSON serializable

[Unit 193]

Howdy,

This is fixable with a very simple patch, though I'm not sure what the
downside of it is:

Title:
  "pastebinit -i file" to paste.openstack.org fails: Object of type
  'bytes' is not JSON serializable

Status in pastebinit package in Ubuntu:
  New

Bug description:
  pastebinit from a file to paste.openstack.org fails:

  paulo:~/tmp$ pastebinit -i /etc/lsb-release -b paste.openstack.org
  Traceback (most recent call last):
    File "/usr/bin/pastebinit", line 417, in <module>
      params = json.dumps(params)
    File "/usr/lib/python3.6/json/__init__.py", line 231, in dumps
      return _default_encoder.encode(obj)
    File "/usr/lib/python3.6/json/encoder.py", line 199, in encode
      chunks = self.iterencode(o, _one_shot=True)
    File "/usr/lib/python3.6/json/encoder.py", line 257, in iterencode
      return _iterencode(o, 0)
    File "/usr/lib/python3.6/json/encoder.py", line 180, in default
      o.__class__.__name__)
  TypeError: Object of type 'bytes' is not JSON serializable

  It doesn't seem to depend on the file type: I tried with quite a few
  and the error was the same each time.

  It works as expected when reading from stdin:

  paulo:~/tmp$ cat /etc/lsb-release | pastebinit -b paste.openstack.org
