Bug Description

While creating the image if user passes property 'key' greater than 255 characters then it fails with 500 error. Ideally it should return 400 Bad Request to the user.

Steps to reproduce:
1. Create image
glance image-create --name mySignedImage --container-format bare --disk-format qcow2 --property "abccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccc"="12434" --file ~/devstack/local.conf

Output:
500 Internal Server Error: The server has either erred or is incapable of performing the requested operation. (HTTP 500)

It would be nice if we could upgrade our jsonschema/jsonpatch support in Rocky.

With jsonschema draft04, we can do something like this:

replace
     "additionalProperties": {"type": "string"}

with
   "patternProperties" : {
     "^.{1,255}$": {
       "type": "string",
       "maxLength": 255}
     },
    "additionalProperties": false

This would force all properties (keys) not explicitly defined in the schema to have the 255 maxlen restriction for both key and value, and it would be de facto backward compatible (because even though the current schema allows you to specify a key > 255 char, Glance does not allow you to actually do it). But I think it's too late in the cycle to try this.

    Fix 500 if custom property name is greater than 255

    If user passes property 'key' greater than 255 characters
    then it fails with 500 error.

    Modified request deserializer to check if custom property key
    is greater than 255 characters then raise HTTPBadRequest with
    appropriate error message.
