aqa-tests: Parse problem list and generate json file

As part of Create a Disabled tests pipeline, we need to parse openjdk problemlist and get json file:

• input: problem list https://github.com/adoptium/aqa-tests/tree/master/openjdk/excludes
• expected output:

[{
"JDK_VERSION" : 17,
"JDK_IMPL" : "hotspot",
"TARGET" : "jdk_custom",
"CUSTOM_TARGET" : "java/lang/ClassLoader/nativeLibrary/NativeLibraryTest.java",
"GIT_ISSUE" : "https://github.com/adoptium/temurin-build/issues/248",
"PLATFORM" : "all"
},{
"JDK_VERSION" : 16,
"JDK_IMPL" : "openj9",
"TARGET" : "jdk_custom",
"CUSTOM_TARGET" : "java/lang/ClassLoader/Assert.java",
"GIT_ISSUE" : "https://github.com/eclipse-openj9/openj9/issues/6668",
"PLATFORM" : "x86-64_mac"
}]
