glance-cache-cleaner/pruner is executed in multiple containers at the same time

[Takashi Kajinami]

Description
===========
When GlanceCacheEnabled is true, the following glance-cache commands are executed by the glance_api_cron container.

The glance_api_cron container is deployed on every controller node, thus if a deployment has multiple controller nodes, then the cron job can be executed at the exactly same timing in multiple nodes.
This is not ideal and can cause conflict/unsuitability.

Steps to reproduce
==================
* Deploy overcloud node with multiple controller nodes and GlanceCacheEnabled: true
* Check cron jobs in glance_api_cron container

Expected result
===============
* The glance-cache-cleaner/pruner commands are executed at different timings

Actual result
===============
* The glance-cache-cleaner/pruner commands are executed at the exact same timing

Environment
===========
* N/A

Logs & Configs
==============
* N/A

    Glance: Avoid simultaneous clean/pruner job

    This change introduces randomized delays to cache clean/pruner job
    commands so that these commands are not executed simultaneously in
    multiple nodes.
