[DEA] Explore using graalVM

[mahalakshme]

Goals:

• To improve performance by executing rules on GraalVM (DEA subject profile render)
• Easy maintenance of code - Eg: no need authentication mechanism, etc.,

Analysis:

Because of the below reasons, using graalVM doesn't seem to be worth based on cost-benefit analysis:

• In the rules we use openchs-models. Hence we map the server response to JS model objects in rules-server before being able to call methods on openchs-models.
• We need entities related to the context of the rule, eg: for say decision rule to be able to execute the rule, which are fetched from server db.

AC:

• Validate the above and see if we would get any benefits by using GraalVM

Inputs:

• short-circuited code
• Java upgrade needed
