LocalTime should generate "time" schema instead of "date-time"

[jaisonpjohn]

When I am generating Swagger spec for a LocalTime Java Object I wanted to get
"format" : "time" instead of "format" : "date-time".
otherwise it was tripping off a codegen-from-swagger on consumer side.

I have submitted a PR for the same #104

@jaisonpjohn ah sorry for skipping this. Will add to my (somewhat long, arguably... :) ) W-I-P list at https://github.com/FasterXML/jackson-future-ideas/wiki/Jackson-Work-in-Progress

@cowtowncoder No worries, Thank you.

@jaisonpjohn Finally found time to finish this: I ended up doing manual merge to get this in 2.10, and added some baseline unit testing (just for this and couple of other types). Thank you again for submitting this, it'll get in 2.10.0.
