What problem does this PR solve?

Issue Number: close #212

What is changed and how it works?

• Expose -search.maxUniqueTimeseries to users. This is done by adding a new item to the configuration file.
• Also add -retentionPeriod to the configuration file. (Note: cmdline arg take precedence over configuration file.)
• Upgrade vm to v1.76.1 for -search.maxUniqueTimeseries to take effect.

Example:

# config.toml
# ...

[tsdb]
# Data with timestamps outside the retentionPeriod is automatically deleted
# The following optional suffixes are supported: h (hour), d (day), w (week), y (year).
# If suffix isn't set, then the duration is counted in months.
retention-period = "1"
# `search-max-unique-timeseries` limits the number of unique time series a single query can find and process.
# VictoriaMetrics(tsdb) keeps in memory some metainformation about the time series located by each query
# and spends some CPU time for processing the found time series. This means that the maximum memory usage
# and CPU usage a single query can use is proportional to `search-max-unique-timeseries`.
search-max-unique-timeseries = 300000
