Function `ValidateTemplates`, used on the vmalert startup,
is supposed to check whether used templates and functions
in loaded rules are correct. The function was parsing
and executing loaded templates.
However, rules may contain functions which can't be executed
without values (label values or query results), like `slice`.
Because of this, validation for completely valid expression
`{{ slice $labels.job 9 }}` will fail since `$labels.job`
is empty during validation.
This PR updates `ValidateTemplates` function to only parse
templates without executing them.

add progress bars to the VM importer
The new progress bars supposed to display the processing speed per each
VM importer worker. This info should help to identify if there is a bottleneck
on the VM side during the import process, without waiting for its finish.
The new progress bars can be disabled by passing `vm-disable-progress-bar` flag.
Plotting multiple progress bars requires using experimental progress bar pool
from github.com/cheggaaa/pb/v3. Switch to progress bar pool required changes
in all import modes.
The openTSDB mode wasn't changed due to its implementation, which implies individual progress
bars per each series. Because of this, using the pool wasn't possible.

* Export "null" in jsonl instead of NaN
The NaN appeared because of staleness markers that were added for compatibility. I think it's better to use json `null`, implemented here.
Also maybe it also makes sense to add a flag like `?skip-staleness-markers=true` to `/export`, to skip nulls at all?

The diskUsage stats panel was showing disk usage without including
size of the index, which is not correct. The filter was removed
to reflect the total disk usage.

* dashboards: replace fixed interval of `5m` for `rate` expressions
Before we used fixed `5m` interval for expressions with `rate` func.
Unfortunately, this interval wasn't a fit for all the cases. So we
switch to `$__rate_interval` instead.
