Reduce image size

[kariya-mitsuru]

Comprehensive Summary of your change

Do following actions to reduce the size of the generated images.

• Change COPY command + chown/chmod command to COPY command + --chown/--chmod option. To prevent both files before/after chown/chmod commands from being recorded on different layers.
• Put all tdnf commands in a single RUN command and move tdnf clean all command to the end. To prevent the tdnf cache from being recorded on a layer, and the tdnf database from being recorded on multiple layers.
• Add --link option to COPY command. This does not contribute to image size reduction, but makes image building more efficient.
• Move chown /etc/pki/tls/certs to the Dockerfile.base. This does not contribute to image size reduction, but is used in conjunction with COPY --link to make image building more efficient.

The target images and their sizes are as follows. (The sizes are the value when built locally)

• harbor-core : 185MB -> 118MB
• harbor-db : 285MB -> 263MB
• harbor-exporter : 108MB -> 79.1MB
• harbor-jobservice : 159MB -> 105MB
• harbor-registryctl : 160MB -> 104MB
• redis-photon : 179MB -> 170 MB
• standalone-db-migrator : 328MB -> 284MB

Note that harbor-log, harbor-portal, and nginx-photon have almost no effect, and prepare is not directly executed by the user, so they are not included.

Also, registry-photon and trivy-adapter-photon are not included, since PR #20622 and PR #20623 include equivalent action for these two, respectively.
