[Alexa] Enable spotify tool in Alexa for more countries and areas

[consusilva_97]

I've always have used spotify for listening to music,  now i just bought an Alexa devise for my house.  In order to link spotify as my predetermined music player the skill is not available in my geographic area, in this case Chile. I've looked some questions online and it seems to be not the only country with this problem, since i saw a issue about India with the same situation. 

Thanks
