This is a fix to an unfortunate bug introduced by #64 because we had a
default value set to `None` on the
`clever_haskell_entry_point`. Ansible considers `None` as a defined
value so the `is defined` condition doesn't match our need
Example: `{ name: pg, env_prefix: POSTGRESQL_ADDON }`
- `clever_app_tasks_file`: tasks file to be executed after environment and addons variables where gathered. Specific to an app, should be use to run migrations. Optional.
- `clever_haskell_entry_point`: the haskell executable name to be executed by clever cloud, optional.
-- _Obsolete_: `clever_entry_point`: Same as above but was replaced by `clever_haskell_entry_point` since v1.14 of this role.
- `clever_domain`: the domain from which the application should be reachable, optional.
- _Obsolete_: `domain`: Same as above but was replaced by `clever_domain` since v1.4 of this role.
- `clever_syslog_server`: UDP Syslog server to be used as UDPSyslog drain for the application, optional. Example: `udp://198.51.100.51:12345`.
