[EWG] - Can now configure any line in nexus.properties by setting the…

… appropriate key in the 'nexus_properties' dict

[2] Also fixed an issue whereby we weren't setting the permissions and ownership on the installation directory correct.
[3] Also set the nexus user's default shell to '/bin/bash' as it is required to log in as this user to start Nexus

 - **nexus_installation_dir**: installation prefix that will be used on installation hosts. Defaults to *'/usr/share'*
 - **nexus_work_dir**: working directory, aka sonatype-work
 - **nexus_port**: TCP port
+- **nexus_manage_os_user**: Boolean value which controls whether the nexus o/s user is managed by the Playbook. Defaults to true.
+- **nexus_os_user**: The name of the nexus o/s user to create/ manage when ``nexus_manage_os_user`` is true. Defaults to 'nexus'.
+- **nexus_manage_os_group**: Boolean value which controls whether the nexus o/s group is managed by the Playbook. Defaults to the value of ``nexus_manage_os_user``.
+- **nexus_os_group**: The name of the nexus o/s group to create/ manage when ``nexus_manage_os_group`` is true. Defaults to 'nexus'.
+- **nexus_os_user_shell**: The shell to set for the nexus user. Only effective when when ``nexus_manage_os_user`` is true. Defaults to '/bin/bash'
+- **nexus_properties**: A dict containing key/ value pairs to be written in to ``nexus.properties``. By default this will contain the keys/values specified in ``defaults/main.yml``, however this can be overridden to contain arbitrary keys/values. Note: Ansible does not merge dicts by default so if you provide *any* keys/values then the ones in ``defaults/main.yml`` will not be used and must be re-specified in your dict to be included, (unless you have switched on [hash merging][1] of course). If you re-implement this dict with custom values you _must_ specify a value for the ``nexus-work`` key, even if you stick to the default location.
