* vmselect: introduce `search.skipSlowReplicas` cmd-line flag
vmselect has two logical conditions during request processing when
`-replicationFactor` cmd-line flag is set:
1. If at least `len(storageNodes) - replicationFactor` responded, it could skip
waiting for the rest of nodes to respond. This could lead to problems described
here https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1207.
2. Mark response as partial if less than `len(storageNodes) - replicationFactor` responded
without an error.
The P1 showed itself error-prone and became the main reason why
`-replicationFactor` wasn't recommended to use at vmselect level.
However, this optimization could be still very useful in situations
when there are slow and fast replicas in cluster.
But P2 remains viable and important conditionless.
Hiding P1 behind the feature-flag `search.skipSlowReplicas`
should make `-replicationFactor` flag usable again. And let users
choose whether they want P1 to be respected.

vmalert: allow disabling of `step` param attached to instant queries
This might be useful for using vmalert with datasources that to not support this param,
unlike VictoriaMetrics.

- Clarify the scope of the fix at docs/CHANGELOG.md
- Handle the case when -search.maxSamplesPerSeries limit is exceeded
in the same way as the -search.maxSamplesPerQuery limit.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4472
libcrypto3 and libssl3 in Alpine 3.18.0 have versions `3.1.0-r4`
which contains CVE-2023-2650:
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-2650
Use ALpine image 3.18.2 which contains fixed versions of libssl3
and libcrypto3: 3.1.1-r0
NB: In Openshift these containers are marked as vulnerabilities
because of these CVEs.
