[SLF4J-437] Add BOM module for better dependency management

[Prototik]

BOM's used to keep in sync versions of dependencies. You can read more info here

Example usage (Maven):

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-bom</artifactId>
      <version>${slf4j.version}</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>
...
<dependencies>
  <dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
  </dependency>
  <dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-simple</artifactId>
  </dependency>
  <!-- whatever else -->
</dependencies>

Example usage (Gradle):

dependencies {
  api(platform("org.slf4j:slf4j-bom:$slf4j_version"))

  api("org.slf4j:slf4j-api")
  api("org.slf4j:slf4j-simple")
}

Any plans for merge?

Yes curious about merge too

Bumped into this today, slf4j is the only BOM-less dependency in the project.

Would love to see this.
