Extract Distinguished Name from Keystore - SSL Mutual Auth does not respect " " when removing spaces

[putz612]

Describe the issue
We have an issues where our DN's have a space between quotes do to a comma in the OU. When enabling RBAC the sed line to remove spaces does not respect that that things between quotes need to stay that way so it will fail authorizing the broker.
https://github.com/confluentinc/cp-ansible/blob/7.3.4-post/roles/kafka_broker/tasks/set_principal.yml#L28-L41

To Reproduce
Have a DN in this from
CN=server.test.domain,OU=testO="My CO, LLC ",L=Minneapolis,ST=MN,C=US
will become
CN=server.test.domain,OU=testO="My CO,LLC ",L=Minneapolis,ST=MN,C=US

Expected behaviour
Keep white spaces between ""
