nixos/atlassian-jira: allow to store SSO password for crowd outside of the Nix store

The option `services.jira.sso.applicationPassword` has been replaced by
`applicationPasswordFile` that needs to be readable by the `jira`-user
or group.

The new `crowd.properties` is created on startup in `~jira` and the
secret is injected into it using `replace-secret`.
