Multiple MyQ Hubs
**Is your feature request related to a problem? Please describe:**

Cannot seem to add multiple MyQ hubs with separate login information from one another. 

**Describe the solution you'd like:**
Ability to add more than one MyQ hubs to the plugin

**Describe alternatives you've considered:**
I have tried running another MyQ/Chamberlain plugin but they have not been updated in a long time so they do not work at all. 

**Additional context:**
Thank you for all the contribution to the plugin!
