Property consolidation

There are many unique property names to Grommet that could be aligned better with the web specification. For instance the property a11yTitle is odd since it has numbers and is an abbreviation of accessibility. I would expect this property to be named ariaLabel.

Other examples of uniquely named props:

• gap vs margin
• pad vs padding
• tag vs as

A suggestion would be to consolidate the properties over the course of two full major version changes. In v3 introduce deprecation warnings for using the old props with suggestions for the new ones, possibly produce a codemod to do this for your users, and in v4 completely remove the old props.

I agree with deprecating a11yTitle and rely on aria-label instead.

I like gap and pad.
