Sunstone: Add setting to hide version number

[xBytez]

Description For security, we'd like to not disclose the version information to the user/login page. I suggest adding a sunstone-server setting to be able to hide.

Use case Just for security reasons we wish to not show version numbers (we do this for nginx too by using server_tokens off;.

Interface Changes The interface would simply show "OpenNebula by OpenNebula Systems" rather than "OpenNebula 5.8.1 by OpenNebula Systems" if this setting is turned on.

Additional Context I notice that the current version is also used when including some resources like JavaScript or stylesheets. We have to think of a good alternative (timestamp of some sorts?).
