Add ability to add multiple Phone numbers to facilities

[fabionl]

Facilities can have many phone numbers.

Each phone number record will have the phone number and a notes.

This will have to be done in 2 steps.

• Implement the logic to allow for adding multiple phone numbers with validation.
• As part of deployment, copy the current phone number to the new phone number data. Just log a warning if the phone number is not valid.
• After deployment, admin will fix the facilities data.
• Remove the old facilities phone number field.
