lib/streamaggr: add option to ignore first N aggregation intervals (#6137) 
Stream aggregation may yield inaccurate results if it processes incomplete data. 
This issue can arise when data is sourced from clients that maintain a queue of unsent data, such as Prometheus or vmagent.
 If the queue isn't fully cleared within the aggregation interval, only a portion of the time series may be included in that period, leading to distorted calculations. 
To mitigate this we add an option to ignore first N aggregation intervals. It is expected, that client queues
will be cleared during the time while aggregation ignores first N intervals and all subsequent aggregations
will be correct.

.github: move pull_request_template.md from .github/PULL_REQUEST_TEMPLATE/ to .github/ 
I couldn't figure out how to show the provided pull request template to users
according to https://docs.github.com/en/communities/using-templates-to-encourage-useful-issues-and-pull-requests/creating-a-pull-request-template-for-your-repository ,
I let's try 'global pull request for the whole repository' approach.

Move CONTRIBUTING.md to docs/ 
It is better from visibility PoV if the CONTRIBUTING.md file is visible at https://docs.victoriametrics.com/contributing/ .
This page can be indexed by search engines and searched by our users later.
It is also easier to provide a link to this page now comparing to the old link, which is much harder to remember:
https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/CONTRIBUTING.md

While at it, syncrhonize docs/CONTRIBUTING.md with .github/PULL_REQUEST_TEMPLATE/pull_request_template.md ,
so they do not contain duplicate information, which can be outdated over time. Now all the relevant information
is located at docs/CONTRIBUTING.md, while .github/PULL_REQUEST_TEMPLATE/pull_request_template.md refers this doc.

lib/protoparser: substitute hybrid channel-based pools with plain sync.Pool 
Using plain sync.Pool simplifies the code without increasing memory usage and CPU usage.
So it is better to use plain sync.Pool from readability and maintainability PoV.

app/vminsert/influx: replace hybrid channel-based pool+sync.Pool with plain sync.Pool for pushCtx 
The memory usage for plain sync.Pool doesn't increase comparing to the memory usage for the hybrid scheme,
so it is better to use plain sync.Pool in order to simplify the code and make it more readable and maintainable.

app/vmagent/influx: replace hybrid channel-based pool + sync.Pool with plain sync.Pool for pushCtx 
Data ingestion benchmark doesn't show memory usage difference between two approaches,
so let's use simpler approach in order to improve code readability and maintainability.

app/vmagent/common: use plain sync.Pool instead of a mix of sync.Pool with channel-based pool for PushCtx 
This scheme was used for reducing memory usage when vmagent runs on a machine with big number of CPU cores
and the ingestion rate isn't too big. The scheme with channel-based pool could reduce memory usage,
since it minimizes the number of PushCtx structs in the pool in this case.

Performance tests didn't reveal significant difference in memory usage under both low and high ingestion rate
between plain sync.Pool and the current hybrid scheme, so replace the scheme with plain sync.Pool in order
to simplify the code.

app/vmalert: make TestGroupStart more reliable (#6130) 
There was a sleep statement in the test, waiting for Group
to perform a couple of evaluation. But looks like
it worked unreliable for some CI tests like the one below
https://github.com/VictoriaMetrics/VictoriaMetrics/actions/runs/8718213844/job/23915007958?pr=6115

This commit changes the sleep statement on a function that
waits for a specific number of evaluations. It should make this
test faster in general case, and more reliable for slow environemnts.

lib/storage: search for all the values for the given label before applying filters and limits
