* Optimize linking of foreach alarms to dimensions.
Keep the write-lock on host but use read-lock for charts because it's
easy to verify that they aren't modified by the linking of foreach
alarms to dimensions.
* Protect alarm log modifications with write-lock.
|

After https://github.com/netdata/netdata/pull/12209 per-chart configuration
was used for (a) enabling/disabling a chart, and (b) renaming dimensions.
Regarding the first use case: We already have component-specific
configuration options|flags to finely control how a chart should behave.
Eg. "send charts matching" in streaming, "charts to skip from training"
in ML, etc. If we really need the concept of a disabled chart, we can
add a host-level simple pattern to match these charts.
Regarding the second use case: It's not obvious why we'd need to provide
support for remapping dimension names through a chart-specific configuration
from the core agent. If the need arises, we could add such support at
the right place, ie. a exporter/streaming config section.
This will allow each flag to act indepentendly from each other and
avoid managing flag-state manually at various places, eg:
```
if(unlikely(!rrdset_flag_check(st, RRDSET_FLAG_ENABLED))) {
rrdset_flag_clear(st, RRDSET_FLAG_UPSTREAM_SEND);
rrdset_flag_set(st, RRDSET_FLAG_UPSTREAM_IGNORE);
} ...
```

* check for chart obsoletion on children connections
* use rrdset_is_obsolete
|
|
* filter
* update filter
* queue removed directly
* more
* logging
* cleanup
* cleanup 2
* cleanup 3
* finalize instead of reset
|
|
* store alarm log entries even if it is repeating
* log times repeated for an alert
|
|
* Add timeout parameter in queries and in calling functions
* Add CANCEL flag in RRDR and code to cancel a query
* Update swagger
* Format swagger file properly
|
|
The previous approach required us to try wr-lock the host
after locking a chart and sleeping on failure. Lock contention
would lead to alarms not being created and the agent to become
unresponsive.
