Remove read-only from customer role in REST API

[amirvenus]

Is your feature request related to a problem? Please describe.
I'm always frustrated when I have to create a customer using the REST API and then having to change its role as the WC one is read-only.

Describe the solution you'd like
Remove read-only from Customer-> role in the REST API

Describe alternatives you've considered
For now, I have to either modify the database to change the customer's role or use the Wordpress's API to do so.

Alternatively, the role can be changed using the WC Admin page and I wonder why it's read-only on the API!

Those aren't the only options, there's filters to enable it.
You can find all functions and filters to change it in:

Closing because for now we don't plan to open the REST API for everyone, since this may cause security problems for some people.
