app/vmselect/prometheus: add -search.ignoreExtraFiltersAtLabelsAPI command-line flag for ignoring extra_filters and extra_label args at /api/v1/labels, /api/v1/label/.../values and /api/v1/series 2024-02-29 13:00:24 +02:00

app/vmselect: add -search.maxLabelsAPIDuration and -search.maxLabelsAPISeries options for fine-tuning CPU and RAM usage for /api/v1/series , /api/v1/labels and /api/v1/label/.../values 
This commit returns back limits for these endpoints, which have been removed at 5d66ee88bd ,
since it has been appeared that missing limits result in high CPU usage, while the introduced concurrency limiter
results in failed lightweight requests to these endpoints because of timeout when heavyweight requests are executed.

all: add support for or filters in series selectors 
This commit adds ability to select series matching distinct filters via a single series selector.
For example, the following selector selects series with either {env="prod",job="a"}
or {env="dev",job="b"} labels:

  {env="prod",job="a" or env="dev",job="b"}

The `or` filter is supported in all the VictoriaMetrics tools now.

app/vmselect/searchutils: accept partial RFC3339 values at time, start and end query args 
This simplifies manual usage of the APIs. For example, the following query
would return the results over the 2022 year.

  /api/v1/query_range?start=2022&end=2023&step=1d&query=...

This is equivalent to:

  /api/v1/query_range?start=2022-01-01T00:00:00Z&end=2023-01-01T00:00:00Z&step=1d&query=...
