at-a-glance: multiple fixes to mon/osd/growth and forecast panels
MON/OSD panel queries updated to address the interpolation
problem where floats were shown. OSD panel also now shows
total OSDs
Templating update for the disk_full_threshold (2->80)
Growth/Forecast panel queries updated to account for data coming
from multiple mon's
Health Panel updated to show as RED when the cluster is in an
ERROR state

at-a-glance: pg status pie chart changes
a degraded state is now shown based on the diff of pg_active and
pg_active_clean. This intermediate metric has been added to the pie
chart so it shows; active+clean, degraded and peering.

network-usage: dashboard updated to track enX interface stats
graphite doesn't support blacklisting in queries, so interface names that
we're interested in have to be whitelisted. This fix now tracks enX, ethX and
bondX interface names.

ceph-rados: display fixes to a several charts
health history was a mess with the light theme. The chart now uses threshold lines
(amber and red), and plots health against those lines. In addition small fixes to the capacity

- forecast value if negative now shows N/A
- forecast and growth queries updated
- disks near full set to 0, if there aren't any issues (instead of no value)

status-panel: Update the bkgnd color to support the light theme
By default the panel just uses 'green', which with the light theme is too
dark, making the text on the panel difficult to read. This ansible step just

We need this to pass through the log_level keyword argument to the base

We need to start and communcite with grafana after we push our own

Dashboard updates;
- initial light theme support - some colour changes on charts
- shuffled panel order so the rows basically cover - overview, client and OS

- PG's now shown using Grafana labs pie chart plugin
- count of rbds now shown (on client row)

mon: updated for logging and additional metrics collected for rbd and osd hosts
collector class now scans the cluster to determine the count of RBDs. Each monitor
will pick a discrete set of pools to scan, so the overall load is shared across monitors.
In addition, since the osd tree command is used to determine the up/down state of
the OSDs, the same output is used to determine the number of osd hosts in the
configuration. Prior to this change the determination was inferred through a
graphite query.

at-a-glance: fix for health panel, and colour match with status panel
The singlestat panel was using value map, but singlestat appears to be interpolating
the health value which results in the value map not being used and a number appearing

In addition, cosmetic changes to the health, disk and latency panels - making their warning
colour state match the status panel warning colour for consistency

dashboards updated to account for null missing values
Prior to this change the charts had "Display/Null Value" set as null - but in
an environment where observations/metrics are arriving late or miss, the
resulting chart would be part populated at best, at worst blank with only
hover only providing an indication that data points are present.
Ideally the data should be present - but by setting as connected, null values
will not stop the graphs from being rendered.

at-a-glance : health history chart updated
The health history query lead to interpolation of health values, so you'd see 1,2 or 3's due to averaging. This
