Manteinances API Get endpoint

[abacram]

Hi, first of all thanks for your work. I have been reviewing the api docs and the full library, but i'm not capable to find any endpoint to retrieve the manteinances, could be possible to add it or in case it exists point me to the correct api url?

Thanks!

This would be really great then someone would be able to also implement as a script or cronjob which allows to "autoclose" maintenance windows as requested here #220 and here #296
