Add --change-set-name to aws cloudformation deploy command

[y3ti]

Is your feature request related to a problem? Please describe.

I would like to have CI/CD process which looks like this:

1. Create a new change set for review:

aws cloudformation deploy \
    --stack-name XXX \
    --change-set-name ${BRANCH_NAME}-${BUILD_ID} \
    --no-execute-changeset \
    ...

2. Display what will be changed:

aws cloudformation describe-change-set \
    --stack-name XXX \
    --change-set-name ${BRANCH_NAME}-${BUILD_ID} \
    ...

3. Wait for confirmation
4. Execute change set

aws cloudformation change-set-execute \
    --stack-name XXX \
    --change-set-name ${BRANCH_NAME}-${BUILD_ID} \
    ...

Describe the solution you'd like

I would like to add a new parameter --change-set-name to the deploy command, so CI/CD service can set its own name for the new change set.

Describe alternatives you've considered

1. Use aws cloudformation create-change-set

It doesn't solve problems that deploy command solves, for example I don't need to think about --change-set-type (CREATE or UPDATE).

2. Query (filter) the output of aws cloudformation deploy --no-execute-changeset

A change set name awscli-cloudformation-package-deploy-* is not descriptive and I would like to have better names in logs and CloudFormation UI :)

I can try to impelement this new feature as my first pull request, but first I would like to know what do you think :)
