Added KB examples and tests and updated metadata file

[gausekha]

This pull request adds code examples for the APIs CreateKnowledgeBase, GetKnowledgeBase, UpdateKnowledgeBase, DeleteKnowledgeBase, and ListKnowledgeBases APIs. The same submission was made earlier but running the writeme created a large number of file diffs. This submission hopes to avoid such a large commit.

@gausekha Looks like you're failing the linting at this point. If you can get that fixed up, we should be able to get this merged soon.

@beqqrry-aws Is it this error? Just checking. For some reason, KB requires a certain range of uuid values and I had to add this change for the tests to pass. Do you have any suggestions around this if that's the case?

error:
cannot format python/example_code/bedrock-agent/knowledge_bases/knowledge_base.py: Cannot parse: 68:0: "clientToken": "test-client-token-" + str(uuid.uuid4())

@gausekha

Yes, that looks to be the error. My guess is it's having trouble understanding the concatenation inside of a dictionary value. Try encapsulating the whole thing in an f string instead, so it can be parsed as a single value.

@gausekha , I saw this was still unmerged and I made a couple adjustments to the text and the tests, to get the tests and the PR checks passing again. If you agree with them and comment here, I will merge it.

[gausekha]

Yes, thanks so much @rlhagerm they look good to me! Also, apologies for the delay @beqqrry-aws ! I have been a bit heads down and didn't get a chance to look at the linting issue. I'll try to resolve it this week if possible but if not it may have to wait until next week. Apologies for the delay!

[rlhagerm]

@gausekha , I resolved the linting issue for you also. Merging today.

Awesome, thanks so much for taking care of that as well, Rachel! :)
