vibe-core logging api implementation needs to be removed

Currently, when using vibe-core as dependency and a different logging bridge is used, exclusions are needed. A fix is needed where vibe-core only uses a logging api interface.

Needed code when using as library that uses different logging bridge:

<dependency>
  <groupId>org.molgenis</groupId>
  <artifactId>vibe-core</artifactId>
  <version>${vibe.version}</version>
  <exclusions>
    <exclusion>
      <groupId>org.slf4j</groupId>
      <artifactId>jcl-over-slf4j</artifactId>
    </exclusion>
    <exclusion>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-nop</artifactId>
    </exclusion>
  </exclusions>
</dependency>

Vibe-core maven dependency tree (stripped to relevant parts only):

[INFO] --- maven-dependency-plugin:2.8:tree (default-cli) @ vibe-core ---

Error thrown by molgenis-app-vibe if exclusions are not present:
