[PATCH 8/8] playbooks: Fix host pattern for single-node setups

Change devconfig.yml and update_etc_hosts.yml to use "all:!localhost"
instead of "baseline:dev:service" as the host pattern. This fixes
warnings about unmatched host groups during bringup for single-node
configurations like rcloud-guest-test.

The hardcoded "baseline:dev:service" pattern only works for A/B testing
setups with dedicated service nodes. Single-node setups don't have these
groups defined, causing Ansible to emit warnings:

  [WARNING]: Could not match supplied host pattern, ignoring: baseline
  [WARNING]: Could not match supplied host pattern, ignoring: dev
  [WARNING]: Could not match supplied host pattern, ignoring: service

Using "all:!localhost" works for all deployment scenarios:
- Single-node: runs on the node, skips localhost
- A/B testing: runs on baseline and dev nodes, skips localhost
- With service nodes: includes service nodes, skips localhost

Commmit 1cf0800c9ffce ("gen_hosts: templates: include localhost in the
all group") introduced this new warning and commit 94d0e3157a017
("devconfig: include the "service" group in theplaybooks hosts list")
extended it with the service group.
