` jackson-databind` should not be optional/provided dependency for Properties, YAML modules

[jvanzyl]

In the following pom.xml for jackson-dataformats-properties:

https://github.com/FasterXML/jackson-dataformats-text/blob/master/properties/pom.xml#L23

jackson-databind is not optional, it is required for the JavaPropsMapper to work correctly.

To provide some more details on the issue: I have jackson-dataformat-properties as a dependency and then attempt to call new JavaPropsMapper().readValue(file, MyClass.class) but receive a compiler error:

error: cannot access ObjectMapper class file for com.fasterxml.jackson.databind.ObjectMapper not found

The readValue() method is defined in ObjectMapper, which is the super class of JavaPropsMapper. ObjectMapper is defined in jackson-databind. If I add jackson-databind as an explicit dependency I get an error that the dependency is unused. I'd rather not turn off the check so for now I've added dummy usage of a class from jackson-databind.

Ah yes. For some of dataformats it used to be fully optional (mostly binary codecs), but with 2.10, and especially for Properties, it should be regular full dependency. Will fix for 2.10 and later; check that same is done for CSV and YAML as well -- starting with 2.10, every format has matching XxxMapper to support builder pattern so it can not be optional dependency.
