NFS stats related /proc files should also be gathered

      Description

      Right now, though there are already a decent amount of things retrieved, but this does not get NFS stats if they're available, which can be valuable for diagnosing potential perf related issues.

      Essentially, the missing files are the ones presented also through the nfsstats and mountstats commands:

      • /proc/net/rpc/nfsd
      • /proc/net/rpc/nfs
      • /proc/self/mountstats

      Now:

      cpuinfo.txt
      meminfo.txt
      mounts.txt
      self/
        cmdline
        environ
        limits.txt
        status.txt
      swaps.txt
      system-uptime.txt
      

      NOTE: main issue to watch out/test, probably, is that the current list seems to be unconditionally retrieved. So as those new files may or may not present, we need to make sure the support-bundle generation still works on system where NFS is absent.
      UPDATE: so actually, the standard support-core plugins's FileContent class already handles this: if a file cannot be found, it will carry on and just put a notice that it cannot be found in that file in the zip. Which makes sense in the end indeed: the goal of that plugin being to gather as much things as it can in a prod env. It this fails fast at the first issue, it'd probably be useless.
