HTTPCLIENT-2189 - Cookie and Cache APIs to use Java time primitives.

[arturobernalg]

Change all the remain classes to use Time. API´s.
Remarks:

• There are tests with name Deprecated that indicate that are using a all method (deprecate). They should be removed when you decide to stop supporting to old API´s. This way it is easier to delete all the old code when the time comes.
• I had to add support to the java time package used in Cache entity Serializer/deserializer.
• I tried to keep the same of all variable and method, but in some point was´t possible because the conflict name. I've used xxxInstant, e.g getExpiryInstant
