Remove unused dependencies

[Celebrate-future]

@hai-adatao Hi, I am a user of project io.ddf:ddf_core_2.10:1.5.0-SNAPSHOT. I found that its pom file introduced 78 dependencies. However, among them, 15 libraries (19%) have not been used by your project (the redundant dependencies are listed below). This PR helps io.ddf:ddf_core_2.10:1.5.0-SNAPSHOT lose weight :) I have tested the revised configuration in my local environment. It is safe to remove the unused libraries.

Best regards
