api-ref: value of custom property not limited to 255 chars

[Matt Riedemann]

- [x] This doc is inaccurate in this way: ______

https://developer.openstack.org/api-ref/image/v2/index.html#create-an-image

Where it says:

"Additionally, you may include additional properties specified as key:value pairs, where the value must be a string data type. Keys and values are limited to 255 chars in length. Available key names may be limited by the cloud’s property protection configuration."

The 255 char length restriction is only for keys, not values:
