ceph-salt fails when yaml exceeds 1024 characters

[ebl-nde]

Based on the character limitation described here, adding new minions fails with a pillar render error if the number of minions exceeds the total number of 1024 characters.

The ceph-salt-top.sls content is generated here:

class PillarManager:

    CS_TOP_FILE = "ceph-salt-top.sls"
    CS_TOP_INCLUDE = "{% include 'ceph-salt-top.sls' %}"
    CS_TOP_CONTENT = """{% import_yaml "ceph-salt.sls" as ceph_salt %}
{% set ceph_salt_minions = ceph_salt.get('ceph-salt', {}).get('minions', {}).get('all', []) %}
{% if ceph_salt_minions %}
  {{ ceph_salt_minions|join(',') }}:
    - match: list
    - ceph-salt
{% endif %}

This modification seems to work:

{% set ceph_salt_minions = ceph_salt.get('ceph-salt', {}).get('minions', {}).get('all', []) %}
{% if ceph_salt_minions %}
{% for minion in ceph_salt_minions %}
  {{ minion }}:
    - ceph-salt
{% endfor %}
{% endif %}
