[flare][auto-discovery][jmx] missing attributes-related log files in flare

[truthbk]

In a flare when running jmxfetch in autoconf/auto-discovery mode we don't seem to include the relevant list_everything, list_collected_attributes, list_matching_attributes, etc.

The problem has two facets I believe:

1. JMXfetch will rely on the yamls present to to decide if it calls jmxfetch to collect the attributes matching, etc. So we don't even make the call if those files are not present.
2. Because a new JMXfetch process is launched to collect the attributes, this won't work with SD, because even if JMXfetch was indeed summoned by the flare command, it won't know what attributes to collect.

Ideally we could solve this with gRPC (or similar), currently, it might require some ugly work.
