Feature Request: Auto-generate field labels if none specified

[jmikrut]

Feature Request

Auto-generate field labels based on the field's name. Allow for labels to be disabled by passing false to the label field property.

Use-Case

It gets a bit tedious to specify field labels over and over, when the name of the field could probably be used and formatted properly to generate a field label automatically.

By generating field labels automatically during field sanitization, there will be less configuration necessary by the developer.

Additional Detail

We need to make sure to adjust the field schema validation and field type(s) to support either strings or booleans to be passed to the label property of all fields that support labels.

We also need to make sure to update Field documentation with the corresponding API changes.
