Coming into OSDMonitor::parse_erasure_code_profile() will trigger an assert that probably should be an error instead.

The assert is essentially checking whether "plugin" is defined on the map. Instead, this should return an error if `plugin` is not defined.

Nevertheless, the trigger lies with parsing the `osd_pool_default_erasure_code_profile` config option map.

In this case, the map is actually parsed, but given the default value is

'plugin=jerasure technique=reed_sol_van k=2 m=1 crush-failure-domain=osd'

as assimilated from ceph.conf, the map turns out to be

$6 = std::map with 5 elements = {
  ["'plugin"] = "jerasure",
  ["crush-failure-domain"] = "osd'",
  ["k"] = "2",
  ["m"] = "1",
  ["technique"] = "reed_sol_van" 
}

Note how we have an extra single quote on `plugin` and `osd`. The map should have been parsed so that neither would have that extra character. This may also indicate we either have a bug in `get_json_str_map` or we need to change how the value is provided to the config option.
