Changed the JDK 17 and earlier dockerfiles to download the binaries f…

…rom cloud.oracle.com, using download tokens, instead of having to be manually updated for all CPUs. Dropped the Oracle Linux 7 dockerfiles. Some dockerfiles had an extension with the Oracle Linux name but the "default" ones did not. Normalized it so that all Dockerfiles now indicate which version of Oracle Linux they use."

 # ORACLE DOCKERFILES PROJECT
 # --------------------------
 # This is the Dockerfile for Oracle JDK 11 on Oracle Linux 8
 #
+# ARGS
+# ----
+# This docker file requires two arguments:
+# 1) JDK11_TOKEN is a valid dowload token for JDK 11.  It can be created in cloud.oracle.com/jms under Java Download
+# Token generation is documented on https://docs.cloud.oracle.com/en-us/iaas/jms/doc/java-download.html
+# 2) OCI_REGION is the Oracle Cloud Infrastucture (OCI) region where the token is generated.
+#
 # REQUIRED FILES TO BUILD THIS IMAGE
 # ----------------------------------
+# This dockerfile will download a copy of latest version of JDK 11 from
+#	https://javamanagementservice-download.<OCI_REGION>.oci.oraclecloud.com/java/11/latest/
 #
-# (1) jdk-11.XX_linux-x64_bin.tar.gz or jdk-11.XX_linux-aarch64_bin.tar.gz
-#     Download from https://www.oracle.com/java/technologies/downloads/
+# It will use either x64 or aarch64 depending on the target platform
 #
 # HOW TO BUILD THIS IMAGE
 # -----------------------
-# Put all downloaded files in the same directory as this Dockerfile
 # Run:
-#      $ docker build -t oracle/jdk:11 .
-#
-# This command is already scripted in build.sh so you can alternatively run
-#      $ bash build.sh 8
+#      $ docker build --file Dockerfile.ol8 --tag oracle/jdk:11 --build-arg JDK11_TOKEN=<token> --build-arg OCI_REGION=<region> .
 #
 # The builder image will be used to uncompress the tar.gz file with the Java Runtime.
