"""
This function, creates or updates a symbolic links for epel-release packages.
Creates or updates a symbolic link pointing to the latest release of the epel-release package and another pointing to the next release of the epel-release package.
The symbolic link will be created or updated if:
- There isn't a symbolic link for the latest package;
- Current symbolic link is pointing to an outdated package;
- Current symbolic link is broken;
- There is a file that isn't a link with the same name of the symbolic link.
If the symbolic link is pointing to the latest release already, this function will do nothing.
Parameters:
releases (dict): contains similar information of global variable RELEASES
