lib/storage: stop exposing vm_merge_need_free_disk_space metric
This metric confuses users and has no any useful information.

b8a5ee2e93 lib/{mergeset,storage}: allow merging smaller number of small parts
While this may increase CPU and disk IO usage needed for background merge,
this also recudes CPU usage during queries in production. This is because
such queries tend to read recently added data and it is better to have lower number
of parts for such data in order to reduce CPU usage.

These metrics are:

* vm_small_merge_need_free_disk_space

Previously small parts storage didn't take into account the available disk space for big parts.
