[MDEP-649] dependency:resolve-plugins lacks includeParents user property

**[Dennis Schridde](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=devurandom)** opened **[MDEP-649](https://issues.apache.org/jira/browse/MDEP-649?redirect=false)** and commented

`dependency:resolve` has an `includeParents` user property [1] which `dependency:resolve-plugins` is lacking [2]. This makes it difficult to generate a complete list of all (JARs and) POMs required to build a project (with dependencies and plugins and their dependencies).

P.S. `dependency:get` appears to have a similar shortcoming: It can resolve dependencies recursively (``transitive`=true`, enabled by default [3]), but it lacks a ``includeParents`` user property.

[3]: Which BTW is inverse to the disabled-by-default ``excludeTransitive`` user property of `dependency:resolve`

**Affects:** 3.1.1

Start with the dependency:resolve-plugins goal and compare its documented user properties with dependency:resolve's includeParents option. Then inspect dependency:get and its transitive and excludeTransitive properties; done means the affected goals provide the requested parent-inclusion behavior consistently.
