Rohit Yadav 8cd44b1684 CLOUDSTACK-9467: Add symlink to key file for usage server
On fresh installation, the usage server fails to start if the `key` file does
not exist in its classpath. The issue is reproducible in environments where
the usage server is installed before cloudstack-setup-databases has been called.
Before the cloudstack db has been setup, the key file does not exist at its
default location and installation of usage-server fails to add a symlink to the
key file.

This fix adds a default symlink to `/etc/cloudstack/management/key` if a
symlink/file does not already exist in the /etc/cloudstack/usage directory.

On new installation, in the post-installation steps it checks if the symlink
or file exists, and adds a symlink if it does not exist. On existing
installations, if symlink or file exists then it will skip adding symlink.
