keystone-manage token_flush cron job fails with: expr: division by zero sleep

[Juan Antonio Osorio Robles]

The cron job ends up like this:

[root@controller-0 heat-admin]# cat /var/spool/cron/keystone
# HEADER: This file was autogenerated at 2017-07-31 11:50:18 +0000 by puppet.
# HEADER: While it can still be managed manually, it is definitely not recommended.

# Puppet Name: keystone-manage token_flush
PATH=/bin:/usr/bin:/usr/sbin SHELL=/bin/sh
1 * * * * sleep `expr ${RANDOM} \% 0`; keystone-manage token_flush >>/var/log/keystone/keystone-tokenflush.log 2>&1
# Puppet Name: cinder-manage db purge
PATH=/bin:/usr/bin:/usr/sbin SHELL=/bin/sh
1 0 * * * cinder-manage db purge 0 >>/var/log/cinder/cinder-rowsflush.log 2>&1

which results in an error.

    Use number for KeystoneCronTokenFlushMaxDelay instead of string

    Using a string results in an erroneous check in puppet-keystone, which
    sets up a zero where it shouldn't. So we change it to number to avoid
    that. Note that there will also be a puppet-keystone fix for this.
    Changing the value here assures that deployers only give valid values to
    this parameter.
