repo: Provide one command for the end user

As the process of installing from ERP5 can be controlled with a script,
create such script instead of many steps.

This script is safe to be run many times.

@@ -40,40 +40,8 @@ Usage - instruction to user installing with RPMs
 
 Required machine is CentOS 7.4 with at least Netinstall.
 
-The RPMs shall be downloaded and to one directory, from which all below commands
-will be run.
-
-Procedure, all with `root` user:
-
- * uninstall firewalld: `yum remove -y firewalld`
- * install slapos.node: `yum install -y slapos.node*rpm`
- * add local IPv6: `ip -6 addr add 2001::1/64 dev lo`
- * create directories: `mkdir -p /opt/slapgrid /srv/slapgrid`
- * configure the node: `slapos configure local`
- * kill supervisor: ``kill `cat /srv/slapgrid/var/run/supervisord.pid ```
- * wait a bit: `sleep 5`
- * boot the supervisor: `slapos node instance --now --verbose`
- * wait a bit: `sleep 15`
- * format the machine: `slapos node format --now --alter_user=True`
- * install ERP5 code: `yum install -y erp5*rpm`
-
-Now by using playbook the user can check if all is working:
-
-``ansible-playbook /opt/slapos.playbook/erp5-standalone.yml``
-
-The expected result is:
-
-```
-TASK [standalone-shared : Expose ERP5] ***************************************************************
-ok: [<machine_public_ipv4>] => {
-    "msg": [
-        "Build successful, connect to:",

-        "", 
-        " with", 
-        "  username: zope  password: uqagckyo"
-    ]
-}
-```

-where <machine_public_ipv4> is replaced with public IPv4 of the machine.
