User bob has been created on your control node. Give him the appropriate permissions on the control node. Install the necessary packages to run ansible on the control node.

* The inventory file path is /home/bob/ansible/inventory.
* Ansible should be able to manage 10 hosts at a single time.
* Ansible should connect to all managed nodes using the bob user.
Create an inventory file for the following five nodes:
nodel.example.com
node2.example.com
node3.example.com
node4.example.com
node5.example.com
Configure these nodes to be in an inventory file where node1 is a member of group dev. nodc2 is a member of group test, nodc3 is a member of group proxy, nodc4 and node 5 are members of group prod. Also, prod is a member of group webservers.
