app/vmagent: allow to disabled on-disk persistence ( #5088 )
...
* app/vmagent: allow to disabled on-disk queue
Previously, it wasn't possible to build data processing pipeline with a
chain of vmagents. In case when remoteWrite for the last vmagent in the
chain wasn't accessible, it persisted data only when it has enough disk
capacity. If disk queue is full, it started to silently drop ingested
metrics.
New flags allows to disable on-disk persistent and immediatly return an
error if remoteWrite is not accessible anymore. It blocks any writes and
notify client, that data ingestion isn't possible.
Main use case for this feature - use external queue such as kafka for
data persistence.

* adds test, updates readme
* apply review suggestions
* update docs for vmagent
* makes linter happy

app/vmagent/remotewrite: count maxLabelsPerBlock as 10x of maxRowsPerBlock
...
This should increase block sizes and subsequently increase the maximum possible bandwidth per each connection to remote storage.
This, in turn, should reduce the probability of storing the data in local buffers.

app/{vminsert,vmagent}: add -sortLabels
command-line option for sorting time series labels before ingesting them in the storage
...
This option can be useful when samples for the same time series are ingested with distinct order of labels.
For example, metric{k1="v1",k2="v2"} and metric{k2="v2",k1="v1"}.
