How to change a specific value in file with ansible

Question

I am new to ansible.
I have about 50 servers where I have to change a username and password in the file /etc/nova/nova.conf

Line: 3102 OS_USERNAME = ABC123 (OLD)  
Line: 3103 OS_PASSWORD = xxXXxx (OLD)

with new credentials

Line: 3102 OS_USERNAME = DEF123 (NEW)  
Line: 3103 OS_PASSWORD = vvVVvv (NEW)

I'd use the lineinfile module. For your example above:

- name: Update username in nova.conf
  lineinfile:
    path: /etc/nova/nova.conf
    regexp: '^OS_USERNAME'
    line: OS_USERNAME = DEF123
