minio-chatflow: Support Master/Slave setup

[muhamadazmy]

• First of all make sure to use this flist https://hub.grid.tf/tf-official-apps/minio:latest.flist.md
• The chat flow must give you option to choose between a Single Setup, or Master/Slave setup.

Single setup

This is exactly the same flow as the current chatflow

Master/Slave setup

• Install an extra zdb instance (called tlog) this instance will have an address as namespace:password@ip:port will call it tlog-access in the reset of this issue
• The master minio instance have the same exact config as the current one PLUS
  • Will take a new ENV var called TLOG as TLOG=<tlog-access>
• A new (extra) minio instance will be installed, it should have the same exact config as the master instance (but installs on a different node), plus:
  • It will have exact same setup as the master (without the TLOG env), BUT will have another ENV var MASTER as MASTER=<tlog-access>

I have tried both setups:

1- Single:

• Only one minio is deployed.

2- Master/Salve:

• Two minio are deployed.
• Master can upload/download files and create buckets.
• Slave only can download files.
