Storage: Bucket metadata sample

Bucket metadata sample and test

[frankyn]

One nit.

[frankyn]

This is a Map. How will this be handled?

[JesseLovelace]

It's a Map<String, String>, so the toString function works just fine here, would look like "{k1=v1, k2=v2}"

[frankyn]

Gotcha, thanks for clarifying. Please handle the map through an iterator so the data type is surfaced.

Could you follow this pattern instead?

Lines 1219 to 1224 in 0731387

	if (blob.getMetadata() != null) {
	System.out.println("\n\n\nUser metadata:");
	for (Map.Entry<String, String> userMetadata : blob.getMetadata().entrySet()) {
	System.out.println(userMetadata.getKey() + "=" + userMetadata.getValue());
	}
	}

I misspoke, I should have pointed to this example first.
