Fix to ignore unquoted strings

[eliaoggian]

The script was throwing the following error:

[root@naret-monitor01 ~]# ./upmap-remapped.py
Traceback (most recent call last):
 File "./upmap-remapped.py", line 112, in <module>
   osd_dump = json.loads(osd_dump_json)
 File "/usr/lib64/python3.6/json/__init__.py", line 354, in loads
   return _default_decoder.decode(s)
 File "/usr/lib64/python3.6/json/decoder.py", line 339, in decode
   obj, end = self.raw_decode(s, idx=_w(s, 0).end())
 File "/usr/lib64/python3.6/json/decoder.py", line 357, in raw_decode
   raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 105 column 25 (char 3099)

The output of ceph osd dump -f json | jq -r contained two lines with unquoted strings.

        "score_acting": DBL_MAX,
        "score_stable": DBL_MAX,

As these lines should not be relevant for the script purpose, this change will delete them to allow the correct parsing of the JSON.

Thanks @eliaoggian for this.
These type of issues keep cropping up. I sure wish there was a json library or linter we could use that makes the ceph output parseable.

[eliaoggian]

Yes, even tough I guess the best thing would be to have ceph code producing a valid JSON output straight from the beginning instead of fixing it afterwards 😄

@eliaoggian thanks for this. could you please check if you still need this after we merged #42 ?

[eliaoggian]

Yes, it still fails as there are the unquoted strings.
