Adds instance level API endpoint for downloading maven packages.

Closes #7769 (closed)

How it works

I add 2 dependencies to my pom.xml. Both are stored in GitLab maven repository. Then I add a single instance-level URL for repository.

  <dependencies>
    <dependency>
      <groupId>com.mycompany.app</groupId>
      <artifactId>my-app</artifactId>
      <version>1.0-SNAPSHOT</version>
    </dependency>
    <dependency>
      <groupId>com.mycompany.app</groupId>
      <artifactId>z-app</artifactId>
      <version>1.5-SNAPSHOT</version>
    </dependency>
  </dependencies>
  <repositories>
    <repository>
      <id>gitlab-maven</id>
      <url>http://localhost:3001/api/v4/packages/maven</url>
    </repository>
  </repositories>

So when I install package it will download both dependencies from GitLab

→ mvn -U install
