* Fix Calix OS definitions
The main change is EXA (E7, etc) and B6 (Occam) devices are now their own OS
Now the follow OS exist:
exa: E7 EXA, E5-400, E5-48, E3-48, E3-8G
occamos: B6
Unchanged:
calix: E5-1**, E3-12C
axos: E7-2 AXOS, E9-2, E3-2, E5-520, E5-16F, E3-16F, E5-30x
* fix tests
exa_e7-2 seems like bogus data.
* additional tests, fix an error in the yaml
* Remove extra line return
* Add missed file
* refactor: Updated discovery to use a core module for sysDescr/sysObjectID use
* final update hopefully
* revert changes
* more changes + docs
* migrated poller to use numerical sysObjectID
* more updates for sysObjectID
* update any alert rules which might have enterprises. in
* moved schema file
* small updates
* updated getHostOS()
* scrut fixes
* updated sysObjectId -> sysObjectID
* updated sysObjectId -> sysObjectID
* updated remainder of sysObjectId -> sysObjectID
* another sysObjectId -> sysObjectID
* fixed secureplatform test data
* Fix tests: $device is not pulled from the database before polling
Also, update the db in the core discovery module.
* refactor: Centralize MIB include directory specification
The default is now:
```
$config['mib_dir'].'/mibdirname:'.$config['mib_dir']
```
This means we exclude OS mibs and only use ours (we could prepend `+` if we want to include os mibs.
All snmp calls should only include the name of the subdirectory under the mibs directory.
* Remove d_echo from Proc
Fix snmpsim tests.
