Title: monitoring: host_info: delete a number of metrics

a number of the metrics were just not useful. Delete them.

cpu
---

- cache_size - This looked to be L2 cache size, doubtful people care
- cores_per_socket - no one cares about the number of cores per physical
die

disk
----

- queue, service_time - these seem buggy somehow. Sometimes they were
showing up and other times they weren't. Plus they are dependent on
the last time you called them. Just delete as I think the rtime and
wtime give sufficient insight into the queue

- snaptime- this was the unix timestamp when the metric was snapped. We
need a general hostinfo field for this.

network
-------

- destination - destination of the route, just seemed like a weird thing
to have as it will always be the ip...

- metric - more routing stuff, not used by linux IIRC, delete it.

- speed - not implemented on linux, delete for now

process
-------

- tty - no one cares I think, delete

- processor - this is just going to bounce around in most configurations and not exist for all
non-running processes, delete

filesystem
----------

- type_name - internally kept metric to sigar that is completely out of
date.

system
------

- Drop vendor_code_name, someone can wikipedia it if they want
- Add vendor_name
