Could io.github.scouter-project:scouter-webapp:2.17.1 drop off redundant dependencies?

[Celebrate-future]

Hi! I found the pom file of project io.github.scouter-project:scouter-webapp:2.17.1 introduced 88 dependencies. However, among them, 7 libraries (7%) are not used by your project. I list the redundant dependencies below:

Redundant dependencies

org.glassfish.web:javax.el:jar:2.2.4:compile
javax.xml.bind:jaxb-api:jar:2.3.0:compile
javax.activation:activation:jar:1.1.1:compile
javax.annotation:javax.annotation-api:jar:1.2:compile
javax.inject:javax.inject:jar:1:compile
com.sun.xml.bind:jaxb-impl:jar:2.3.0:compile
javax.el:javax.el-api:jar:2.2.4:compile

Outdated dependencies

javax.inject:javax.inject:1 (5037 days without maintenance)
javax.annotation:javax.annotation-api:1.2 (3746 days without maintenance)
javax.activation:activation:1.1.1 (5027 days without maintenance)
com.sun.xml.bind:jaxb-impl:2.3.0 (2188 days without maintenance)

Removing the redundant dependencies can reduce the size of project and prevent potential dependency conflict issues (i.e., multiple versions of the same library). More importantly, one of the redundant dependencies javax.annotation:javax.annotation-api:jar:1.2:compile induced dependency conflict in the dependency graph. As such, I suggest a refactoring operation for io.github.scouter-project:scouter-webapp:2.17.1’s pom file.

The attached PR helps resolve the reported problem. It is safe to remove the unused libraries (we considered Java reflection relations when analyzing the dependencies). These changes have passed io.github.scouter-project:scouter-webapp:2.17.1’s maven tests.
