Add CLI support to enable Bedrock model access

[avnerv]

Describe the feature

Right now, the only way to enable access to Bedrock foundation models is through the AWS Console.
That’s a bit of a blocker for automation and IaC workflows (Terraform, CDK, etc.) since there’s no CLI command to do the same thing.

Use Case

• Save time in CI/CD setups
• Make multi-account/multi-region deployments smoother
• Avoid one-off console work

Proposed Solution

It would be super helpful to have something like this in the AWS CLI:

aws bedrock enable-model-access \
  --model-ids anthropic.claude-3-opus-20240229:0 amazon.titan-text-g1-express \
  --region us-west-2

Other Information

There’s already a similar ask in the CDK repo (#34850), but this feature would be super useful even for people just using plain CLI.

Hi @avnerv, thanks for reaching out. This type of feature request would need to be implemented by the service team rather than the AWS CLI team. I've forwarded your feedback to the Bedrock team. Please refer to an SDK or AWS CLI changelog for updates about this going forward. Thank you!
