Make Joda DateTime serialization format configurable
We allow the serialization format of dates to be configured using spring.jackson.date-format. However, this property only applies to java.util.Date instances and has no effect on a Joda DateTime. This commit updates our auto-configuration for Jackson to allow the format string that is used to serialize a Joda DateTime to be configured. A new property, spring.jackson.joda-date-time-format has been introduced. When configured, it is used to configure the serialization format for a Joda DateTime. When it is not configured, we fall back to using spring.jackson.date-format. If this fails, either because the format string is incompatible (unlikely) or because the user's configured the fully-qualified name of a DateFormat class, a warning is logged encouraging the use of spring.jackson.joda-date-time-format. Fixes gh-2225
