FIX: remove the docker socket from so-telegraf

so-telegraf mounted /var/run/docker.sock and joined the host docker group on
every node type. The :ro flag blocks write() to the inode, not connect() plus
HTTP over the socket, so any code execution inside the container could reach
POST /containers/create with Privileged:true and become root on the host.

No telegraf script used the socket; the only consumer was the native
[[inputs.docker]] plugin, and group_add 920 existed solely to feed it.
Container metrics now come from so-container-stats, a collector that runs on
the host from cron and writes influx line protocol to a file telegraf already
had mounted. This is the pattern so-status, so-raid-status and
so-elasticagent-status already use, so the privileged docker access stays on
the host side where root cron already ran it.

The collector runs as somon, a service account in the docker group with no
login shell and a locked password, rather than root. Docker group membership
is still root-equivalent on the host, so this is defense in depth rather than
a privilege boundary.

The telegraf scripts were root:939 mode 770, letting socore rewrite them for
code execution inside the container; they are now 750, which still allows the
read and execute telegraf needs. The container also ran with no group, giving
it gid 0, and now runs as 939:939. That alone would have broken
lasthighstate.sh, which reached /opt/so/log/salt only via the root group and
could not tell an unreadable file from a missing one, so it silently reported
a 56 year highstate age. Only the lasthighstate file is bind mounted now, and
the script tests readability instead of existence.

Everything inputs.docker collected beyond the five fields the shipped
dashboards query is available per stat under telegraf:container_stats,
annotated for SOC so an operator can enable it without editing files. Defaults
reproduce the previous output exactly. With every stat enabled the emitted
field set matches what inputs.docker wrote, verified by running the plugin
against the live socket and diffing: 53 fields, no type mismatches, no field
present on one side only.

Two deliberate differences: max_usage carries the real cgroup peak where the
daemon reports 0 on cgroup v2, and host-network containers emit no
docker_container_net row, matching inputs.docker. Docker label tags are not
restored, since nothing queries them and they cost significant cardinality.

so-status, the influxdb size cron, so-elasticagent-status, so-raid-status and
so-common-status-check truncated their output in place while telegraf read it,
so telegraf periodically saw an empty file and logged a parse error or emitted
empty values. They now write aside and rename. Measured on a live manager, the
old so-status cron left status.log empty for 215 of 10997 reads.

Tested on a fresh install, a converted grid and a 3.0 upgrade.
