Number parameter doesn't catch all exceptions

[Thomas Herve]

See the following template:

heat_template_version: pike

parameters:
  a_param:
    type: number
    default: [3, 4]

resources:
  val:
    type: OS::Heat::Value
    properties:
      value: {get_param: a_param}

The default of a_param is wrong, but instead of failing the validation, trying to create a stack returns a server error.

    Catch type errors when casting to int

    Casting a parameter to a number can fail with a type error as well as a
    value error. Let's catch it to get a proper validation error.
