docker: Use JDK17 for SLES dockerfiles

[Haroon-Khel]

• commit message has one of the standard prefixes
• faq.md updated if appropriate
• other documentation is changed or added (if applicable)
• playbook changes run through VPC or QPC (if you have access)
• VPC/QPC not applicable for this PR
• for inventory.yml changes, bastillion/nagios/jenkins updated accordingly

Use JDK17 for the java agent. Use the x64 binary in the dockerfile. The dockernode playbook will change the architecture if needed

LGTM, one note is that the SLES12 dockerfile (Line 3)  has a reference to the SLES 15.4 repository ( I know this is because a support agreement is required to access the SLES12 repositories ).. it should be noted though, that a system built in this fashion will not be a standard SLES12 system, as various packages get much later updates than those available in SLES12 proper.
