dashboards: updates and fixes (#499) 
The new update introduces new row "Troubleshooting" that
contains panels for churn rate and slow-queries/inserts/loads metrics. This row supposed to be reveal the cause of low performance or other issues.

Panels for storage were updated with "bytes-per-datapoint" and "remaining disk size" panels.

vmalert: avoid sending resolves for pending alerts (#498) 
Before the change we were sending notifications to notifier
if following conditions are met:
* alert is in Fire state
* alert is in Inactive state

We were sending Inactive notifications to resolve alert ASAP. 
Unfortunately, we were sending resolves for Pending alerts that become
Inactive, which is wrong.

In this change we delete alert from the active list if
it was Pending and become Inactive. In this way we now
have Inactive alerts only if they were in state Fire before.
See test change for example.

vmalert: fix potential race during configuration reloads (#497) 
Configuration reload and rules evaluation can't be executed
in same time now. This may make reload time longer but
prevents from potential races.

vmalert: fix the access to rules slice element by wrong index (#486) 
During group's update rules deletion was causing slice
mutations while slice index was assumed to be unchanged.
This caused "slice bounds out of range" errors when multiple
rules were deleted sequentially.

vmalert: check if remoteRead object was initied before calling Restore (#473) 
The check for non-nil remoteRead was mistakenly dropped
during refactoring which caused panics when `vmalert`
wasn't configured with `remoteRead` flag.
