Add ability to set enrollment options

[dmaasland]

Hello,

I needed a way to set the enrollment options as specified in the docs here: https://documentation.wazuh.com/current/user-manual/wazuh-dashboard/config-file.html#enrollment-dns

Figured I might as well do a PR so other people benefit as well.

Ah sorry, my prettier extension messed up the readme :(

We have decided not to do this.
