Depends on #7441

Implements new metrics for procfs data, such as memmap count or currently opened file descriptors.
All metrics are provided by the procfs crate.
Since /procfs is not available on non-linux systems, these metrics will only be available if Qdrant is running on linux.

Full list of newly added metrics:

# HELP procfs_mmap_count count of open mmaps
# TYPE procfs_mmap_count gauge
procfs_mmap_count 273

# HELP procfs_current_fds count of currently open file descriptors
# TYPE procfs_current_fds gauge
procfs_current_fds 69

# HELP procfs_soft_limit_fds soft limit for open file descriptors
# TYPE procfs_soft_limit_fds gauge
procfs_soft_limit_fds 1024

# HELP procfs_hard_limit_fds hard limit for open file descriptors
# TYPE procfs_hard_limit_fds gauge
procfs_hard_limit_fds 524288

# HELP procfs_minor_page_faults count of minor pagefaults which didn't cause a disk access
# TYPE procfs_minor_page_faults gauge
procfs_minor_page_faults 56686

# HELP procfs_major_page_faults count of disk accesses caused by a mmap pagefault
# TYPE procfs_major_page_faults gauge
procfs_major_page_faults 19

# TYPE procfs_children_minor_page_faults gauge
# HELP count of minor page faults caused by waited-for children
procfs_children_minor_page_faults 221060

# TYPE procfs_children_major_page_faults gauge
# HELP count of major page faults caused by waited-for children
procfs_children_major_page_faults 5331
