fix: add runtime hints for storage

[zhumin8]

Builds on top of CI setup in #1933. Will rebase once its merged in.

This pr:

• adds runtime hint to storage/integration/aot/StorageIntegrationRuntimeHint.java.
• adds storage module to spring-native profile in pom.xml
• adds storage sample modules & resources to spring-cloud-gcp-samples/pom.xml to run sample test in ci.
• for sample test, point to buckets within the native ci project.

CI:

• sample test should be included in ci that runs with this pr.
• module it test is not included in ci. Below are local test results. you can verify locally by running mvn -Pspring-native,\!default clean test . (adding this ci in fix: add runtime hints for vision #1991)

[UPDATE] The reflection configuration is added in here because the FileUtils class in Spring Integration was calling com.google.cloud.storage.Blob[] (a child class of BlobInfo) reflectively using getClass(). The FileUtils class is invoked by AbstractInboundFileSynchronizer which is a parent of GcsInboundFileSynchronizer The stacktrace that helped with this discovery:

Caused by: java.lang.IllegalArgumentException: Class com.google.cloud.storage.Blob[] is instantiated reflectively but was never registered.Register the class by adding "unsafeAllocated" for the class in reflect-config.json.

Consider a private Resource getResource(Optional<String> filename) function to reduce the duplication in this method and writeGcs.

  @GetMapping(value = "/")
  public String readGcsFile(@RequestParam("filename") Optional<String> fileName)
      throws IOException {
    Resource resource = getResource(fileName);
    return StreamUtils.copyToString(resource.getInputStream(), Charset.defaultCharset()) + "\n";
  }

• Check shortened fixedDelay
• Refactor get() call to have in-scope isPresent() call.
• Keep or replace aot.factories
