This patch adds a "local registry" which is basically a tree of nodes which try to mimic JSON nodes. The idea behind "lreg" is to provide a subsystem which can be used to hold arbitrary objects in a namespace which can be translated into KVs as needed. The first users of the lreg are log entries. The idea here is that each log entry is made into a static object which is installed into a node owned by the respective .c or .h file containing the log message. Later, we will allow users to modify the log levels via external input sources.
Add enum constructor_priorities for specifying the order in which constructor / initialization functions are called at startup. Add support for lreg entries which live in the root. Made macros for defining, declaring, and installing these. There's currently an example in log.[ch]. Cleanup the log.h macros a bit.

APPLY to read-only keys and value filterining on arrays / objects will now return an error via OUTFILE. The code here pretty messy atm and needs some TLC. -- Example #1 $ cat err.cmd GET /entry_map/log_entries@asdfas OUTFILE /err.out $ cat /tmp/.niova/5802f58a-41f2-11ea-a99d-90324b2d1e89/output/err.out { "log_entry_map" : [ { "error" : "May not apply value filter (`asdfas') to array or object (`log_entries')" } ] } -- Example #2 $ cat fault-inj.cmd APPLY frequency_seconds@100 WHERE /fault_injection_points/name@disabled\ injection OUTFILE /err.out $ cat /tmp/.niova/5802f58a-41f2-11ea-a99d-90324b2d1e89/output/err.out { "error" : "Key (`frequency_seconds') is read-only" }

This patch enables the lookout to do some very basic monitoring
operations. The results are reporting through http to the caller.
The reported results are intentionally verbose, the http interface is
meant to provide detailed info about the niova services on the node.
Note there's still a lot of work to do.. For one, the cmd file inputs and
outputs are not being cleaned up. Also, dead enpoints are not yet
removed from the map (perhaps they will remain there forever but with
a lower polling frequency?). Another item is replacing the UUID (used
as a key below) with a short name like "raft-0" or "nosd-1".
Example output:
$ curl -s http://localhost:8080/v0/
