Create a new Neutron Tenant network

A simple script that'll create a new Neutron tenant network for a new user. More below.

Usage:

$ ./create-new-tenant-network.sh                \
                    TENANTNAME USERNAME         \
                    SUBNETSPACE ROUTERNAME      \ 
                    PRIVNETNAME PRIVSUBNETNAME  \

To create a new tenatn network with 14.0.0.0/24 subnet:

$ ./create-new-tenant-network.sh \
  demoten1 tuser1     \
  14.0.0.0 trouter1   \
  priv-net1 priv-subnet1

The script does the below, in that order:

1. Creates a Keystone tenant called demoten1

2. Creates a Keystone user called tuser1 and associates it to the demoten1

3. Create an RC file for user tuser1 and sources the credentials

   $ export OS_USERNAME=tuser1 export OS_TENANT_NAME=demoten1 export OS_PASSWORD=fedora export OS_AUTH_URL=http://localhost:5000/v2.0/ export PS1='[\u@\h \W(keystone_tuser1)]$ '

4. Creates a new private network called priv-net1

5. Creates a new private subnet called priv-subnet1 on priv-net1

6. Creates a router called trouter1

7. Associates the router ('trouter1' in this case) to an existing external network (the script assumes it's called 'ext') by setting it as its gateway.

8. Associates the private network interface to the router.

9. Adds Neutron security group rules for this test tenant for ICMP and SSH.

NOTE: Since the shell script is executed in a subprocess (of the parent shell), you won't notice the keystone sourcing of the newly created user. (You can notice it in the stdout of the script in debug mode -- ./temp-stdout/stdout-new-tenant-creation.txt.)

To test it's all working, you can try boot a new guest in the tenant network, and it should aquire an IP address from 14.0.0.0/24 subnet.
