* deployment/docker/docker-compose.yml: adds version tags for VictoriaMetrics containers
* deployment/docker/docker-compose-cluster.yml: adds version tags for VictoriaMetrics containers
* deployment/docker: move cluster compose env to master branch
The change supposed to simplify the process of maintaining for
single/cluster docker-compose envs, alerts, dashboards. It also
supposes to reduce confusion for users when looking for cluster
related alerts/configs.

Now vmalert will print the following messages on dupliсates:
```
"recording rule \"record\"; expr: \"up == 1\"; labels: summary={{ value|query }}" is a duplicate within the group "test"
"alerting rule \"alert\"; expr: \"up == 1\"; labels: description={{ value|query }}" is a duplicate within the group "test"

* vmalert: always re-evaluate Annotations
Previously, Annotations were evaluated only:
1. On alert creating.
2. On alert's value change.
This is premature optimization. It was assumed that since annotations
could contain only text with alert's labels or value - there is no need
in spending resources to re-compile Annotations.
Later, template function `query` was added, which can execute
arbitrary queries and return different results on every evaluation.
So if it was used in annotations, it would be executed only on init
or value change.
Another case when optimization caused an issue - annotations hot reload.
In this case, annotations of the active alert won't change even if Rule's
annotations were changed.
This fix enables Annotations re-evaluation on each iteration to resolve
issues above. It would have some impact on performance, but it is unlikely
it will be noticeable.

The change adds an example of `curl` command to the Rule's page.
The command is generated for each recorded state. It is supposed
user can just copy&execute the command to see what was returned
to vmalert.

The standard Snappy encoder from github.com/golang/snappy shows quite good performance number
for compressing the Prometheus remote_write proto messages according to the added benchmarks,
so there is no need in switching to github.com/klauspost/compress/s2 yet.

This reduces scrape duration for targets returning big responses.
The response body was already read into memory in stream parsing mode before this change,
so this commit shouldn't increase memory usage.

vmalert: add experimental feature of storing Rule's evaluation state
The new feature keeps last 20 state changes of each Rule
in memory. The state are available for view on the Rule's
view page. The page can be opened by clicking on `Details`
link next to Rule's name on the `/groups` page.
States change suppose to help in investigating cases when Rule
doesn't generate alerts or records.

- Rename logDebug() to logDebugf() and pass format string together
with format args directly to logDebugf(). This eliminates fmt.Sprintf()
overhead at logDebug() call site when debugging is disabled.
- Format labels in debug message in Prometheus format, e.g. {label1="value1",...labelN="valueN"}

* vmalert: add `debug` mode for alerting rules
Debug information includes alerts state changes and requests
sent to the datasource. Debug can be enabled only on rule's
level. It might be useful for debugging unexpected
behaviour of alerting rule.
