Add support for remotectl + parsing results

[RebeccaMahany]

Closes #763

Adds a parser to parse remotectl output.

Example output from querying:

osquery> select * from kolide_remotectl where query = 'Local device/UUID';
+-------------------+--------------+------+--------------------------------------+-------------------+
| fullkey           | parent       | key  | value                                | query             |
+-------------------+--------------+------+--------------------------------------+-------------------+
| Local device/UUID | Local device | UUID | 65978F15-D653-49DF-B0E5-REDACTED     | Local device/UUID |
+-------------------+--------------+------+--------------------------------------+-------------------+

Here's a redacted 2 device dump from my machine. Weirdly, I see that the apple model names (iPhone12,3 and iPhone14,2) don't match the marketed product series (iPhone 11 and 13) 🤷

remotectl.dump.2.devices.txt

Update: and by "2 device" I mean 2 attached devices. So, 3 devices. I have no idea what I was thinking when I named that.

This is looking good!

LGTM! Tested on my own mac including connected to my macbook air.

I didn't stare super hard at the parser, but nothing looked wrong. And it works. LGTM
