Double check gradle version of external test projects as only 7.3 supports jdk17

[sophia-guo]

There are a few external test projects are using gradle with specific version, which might not support jdk17 yet. https://docs.gradle.org/current/userguide/compatibility.html. Need to double check that and if that's the case we need to disable test with jdk17.

Similar to #3381

Can I have this issue assigned to me?

Spring : #3505 (comment)

@sophia-guo
These are all the test that require specific version of grade which doesn't support jdk17.
functional-test - gradle version 5.1
Kafta - gradle version 5.4
Spring - gradle version 5.1
system-test - gradle version 5.1
Should I go ahead and disable these tests for jdk17?

@amir-waheed we can leave functional-test and system-test as is for now.
Both Spring and Kafta actually use gradle wrapper, which means we don't need to manually setup gradle in test.properties file, please see #3530 as spring updates. You can try similar thing for Kafta.

@amir-waheed I also think we can just remove the function print_gradle_install in dockerfile_function.sh as all gradle related projects set up the gradle by gradle wrapper, which we will always use the same gradle version as the application community.

@sophia-guo I have a PR up with these changes.
