PM-404 "En la actualizacion de un plugin no se actualiza el singleton" SOLVED

Issue:
    Al modificar los atributos de un plugin, este cambio no se refleja en el archivo "plugin.singleton" de cada workspace
Cause:
    ProcessMaker no detecta cuando el archivo principal de un plugin es editado
Solution:
    Se ha añdo un nuevo comando, el mismo actualiza el archivo "plugin.singleton" en cada workspace, segun los
    atributos del plugin, el comando es el siguiente:
        $ ./gulliver update-plugin-attributes pluginName
