On the 'how do i apply roles to specific hosts, I'd go for a full
ntp_server role and an ntp_client role.
Then your site.yml looks like
--------------8<---------------
- hosts: ntpservers
roles:
- ntp_server
- hosts: servers
roles:
- ntp_client
- presumably_something_useful
--------------8<------------------
if you want to avoid hardcoding a group into the ntp_client roles
templates, you can pass in a group
name using 'parameterised roles' - though TBH that might be overkill.
the folder layout is then something like (for completeness)
.
├── hosts
├── roles
│ ├── ntp_client
│ │ ├── tasks
│ │ │ └── main.yml
│ │ └── templates
│ │ └── etc
│ │ └── ntp.conf.j2
│ └── ntp_server
│ ├── tasks
│ │ └── main.yml
│ └── templates
│ └── etc
│ └── ntp.conf.j2
└── site.yml
