Log detail for errors could be improved

[MandyBaxter]

Hi, folks.

As a recommendation, consider level-setting system logging details to at least cover anything provided via the gui to the user.

Details:
I just got a pop-up error msg, (Firewall / Aliases / Apply -> "Invalid Argument"). The underlying issue was simply that I'd exceeded the default value for Maximum Table Entries. But, the logging was not helpful to figuring that out. Rambling path to a fix included checking what I'd just changed, deleting the new alias, checking the gui logs (System / Log Files / Backend), checking syslog, checking /var/log/configd.log on the device itself. Nada. Simply, there's no system level logging pertaining to this error. Usually, system level error messages are _more_ verbose than what's presented to the user, not less. (And, definitely not nada.)

The Maximum Table Entries fix was per a suggestion found by search the forum for "invalid argument aliases." (Feature for the discussion forums is awesome, btw.)

On a related matter, there's an inconsistency in what's sent via syslog vs what's reported locally.

Logged messages per System / Log Files / Backend:

/var/log/configd.log has about the same:
configd.log:Oct 28 06:50:11 opnsense configd.py[27022]: [e1c3a420-7add-43f2-869e-6788310a512c] generate template OPNsense/Filter

But, two items are absent per syslog:

NB: In /var/log/configd.log, at least, there are extra, leading spaces in the "message" aspect of the logged records for the two items missing in the syslog'd records. That might be tripping up some log parsing regular expression somewhere?
