Bug on CLI input parsing

Describe the bug

When the short hard syntax has open and closed curly braces in one of the values to the key, the CLI throws following error.

awscli.argprocess.ParamError: Error parsing parameter '--patch-operations': Expected: ',', received: '}' for input:

Expected Behavior

CLI should process the string value as it is.

Current Behavior

@https://github.com/aws/aws-cli/blob/9b6e981407138dc21c4546be10b3eba2a3a61740/awscli/shorthand.py#L136

at this line, regex computed only takes till the closed parenthesis.

e.g, for a key-value of

value=arn:aws:apigateway:us-east-1:lambda:path/2015-03-31/functions/arn:aws:lambda:us-east-1:xxxxxxxxxx:function:Say-hello-world:${stageVariables.version}/invocations

value extracted by the regex is 'arn:aws:apigateway:us-east-1:lambda:path/2015-03-31/functions/arn:aws:lambda:us-east-1:xxxxxxxxxx:function:Say-hello-world:${stageVariables.version'

Reproduction Steps

Create API Gateway REST API with a resource path and method with lambda integration.

try the following command: newuri='arn:aws:apigateway:us-east-1:lambda:path/2015-03-31/functions/arn:aws:lambda:us-east-1:xxxxxxxxxx:function:Say-hello-world:${stageVariables.version}/invocations'

aws apigateway update-integration --rest-api-id xxxxxx --resource-id xxxxx --http-method ANY --patch-operation op="replace",path="/uri",value="$newuri" --debug

This command gives following output:
