bcd3f0c5bd app/vmselect/promql: add hoeffding_bound_upper(phi, m[d]) and hoeffding_bound_lower(phi, m[d]) functions
These functions can be used for calculating Hoeffding bounds
for `m` over `d` time range and for the given `phi` in the range `[0..1]`.

16fb128bbc app/vmselect/promql: do not take into account the previous point before time window in square brackets for min_over_time, max_over_time, rollup_first and rollup_last functions
This makes the behaviour for these functions similar to Prometheus when processing broken time series with irregular data points
like `gitlab_runner_jobs`. See https://gitlab.com/gitlab-org/gitlab-exporter/issues/50 for details.

1c445bf7eb vendor: update github.com/valyala/fastjson from v1.4.2 to v1.4.5
This should fix parsing Inf values in `/api/v1/import`. The previous attempt to fix this in VictoriaMetrics v1.32.1 was unsuccessful.

87a106702b app/vmselect/promql: add aggr_over_time(("aggr_func1", "aggr_func2", ...), m[d]) function
This function can be used for simultaneous calculating of multiple `aggr_func*` functions
that accept range vector. For example, `aggr_over_time(("min_over_time", "max_over_time"), m[d])`
would calculate `min_over_time` and `max_over_time` for `m[d]`.

705af61587 app/{vmbackup,vmrestore}: add backup complete file to backup when it is complete and check for this file before restoring from backup
This should prevent from restoring from incomplete backups.
