e38ca28d99 app/vmselect/promql: increase accuracy for buckets_limit() function for small limits by skipping the first and the last buckets during merge
The first and the last buckets are usually `[0 ... leMin]` and `(leMax ... +Inf)`. If they are merged with adjancent buckets,
then the resulting accuracy can suffer.

    process_io_written_bytes_total - the number of bytes written via io syscalls such as write and pwrite
    process_io_read_syscalls_total - the number of read syscalls such as read and pread
    process_io_write_syscalls_total - the number of write syscalls such as write and pwrite
    process_io_storage_read_bytes_total - the number of bytes read from storage layer
    process_io_storage_written_bytes_total - the number of bytes written to storage layer

These metrics can be used for monitoring process io

9e3993c585 lib/storage: properly hanle regexp tag filters with dots, which can be converted to full string match filters.
For example `{label=~"foo\.bar"}` should be converted to `{label="foo.bar"}`. Previously it has was mistakenly conveted to `{label="foo\.bar"}` .
This could result in missing time series for such tag filters.

7b7963a77f lib/mergeset: unconditionally cache indexdb blocks
Production workloads show that indexdb blocks must be cached unconditionally for reducing CPU usage.
This shouldn't increase memory usage too much, since unused blocks are removed from the cache every two minutes.
