core: Add local configuration helper

This patch adds the LocalConfig class intended to centralize the
management of local configuration stored in the
/etc/sysconfig/ovirt-engine file (or whatever the ENGINE_VARS
environment variable points to).

The name "local" is intended to convey the difference between the
configuration that is specific to a particular node and the
configuration that is "global", stored in the database, and shared
by all the nodes in a (future) cluster.

The intended use is something like this:

  LocalConfig config = LocalConfig.getInstance();
  String myVar = config.getProperty("MY_VAR");

In addition to this generic interface it also supports other
methods to get the values of well known variables, like port
numbers and directories, for example:

  int httpPort = config.getExternalHttpPort();
  int httpsPort = config.getExternalHttpPort();

These methods contain some logic to decide if the external
port is the one used by the web server or the one used by the
application server.
