Telemetry collector for LVE Traffic Accounting (CLOS-4341).
Parses /proc/lve/list and produces a small set of metrics that let us answer:
- does this kernel expose net accounting at all (NETO/NETI columns present)?
- how many user LVEs exist and how many actually accumulated traffic?
- what's the cumulative NETO/NETI volume across user LVEs on this host?
/proc/lve/list contains two non-user LVE rows we exclude from all aggregates:
- *default* (user_id = UINT_MAX) — kernel catch-all for processes not
attached to any specific LVE (sshd, systemd, dnf, ...). Has non-zero
traffic on essentially every running CL host.
- *root* (user_id = 0) — LVE container for root (uid 0). Not a hosting user.
After exclusion the metrics describe user hosting activity, and lves_total
matches the count seen by `lvectl list` and the panel's user list.

LVE ids in /proc/lve/list use the form "<lvp_id>,<user_id>" (e.g. "0,1002")
or just "<user_id>" on older kernels. Malformed rows are excluded.

| d�S ) u� Parse /proc/lve/list text and return the 5 net_acct metrics.
Format of /proc/lve/list:
<version>:<TAB>LVE<TAB>...<TAB>NETO<TAB>NETI # header
<lve_id><TAB>...<TAB><neto><TAB><neti> # one row per LVE
The leading "<version>:" prefix is optional/version-dependent; we tolerate
its presence and absence. NETO/NETI are cumulative byte counters; their
lowercase counterparts lNETO/lNETI are limit columns and ignored here.
skip_user_ids — additional user-id slots to exclude beyond the standard
root/default. Used by cloudlinux-summary to skip its own transient
self-LVE (created via _run_self_in_lve) which would otherwise inflate
counts by 1 on every collection run.
On any structural problem (no header, missing NETO/NETI columns, malformed
rows) we treat the kernel as not supporting net accounting and return a
zeroed result.
