Add support to display usage and limit of all the quotas of an account.

As a user, I would like to see all the usage I got for a given quota and especially I would like to have a ranking to see which quotas are almost filled up.
This would be helpful for customer and support. 

```
scw quota 
DEV1-S=5/10 # in orange
DEV1-M=0/10 # in grey (because not used)
DEV1-L=1/10 # in green
DEV1-XL=9/10 # in red
```
