describe_jobs method on Batch client improperly parses job IDs

The describe_jobs method on the Batch client is supposed to take [a] space-separated list of up to 100 job IDs (source).

However, a botocore.errorfactory.ClientException is erroneously thrown due to the presence of the space delimiting the job IDs. It appears that the client-side validation which enforces that job IDs follow the pattern [a-zA-Z_0-9-]{1,128} is executed before the space separated list of job IDs is split into individual IDs. Rather, it appears that validation is run on the entire string of space-separated IDs.

How to reproduce

response = client.describe_jobs(
    jobs=[
        'a-single-job-id'
    ]
)
# works as expected

response = client.describe_jobs(
    jobs=[
        'one-job-id and-another-separated-by-a-space'
    ]
)
# botocore.errorfactory.ClientException: An error occurred (ClientException) when calling the DescribeJobs operation: Provided name bfed896e-612d-452b-820e-15eaa14d4353,fbf155d0-1bd4-4a01-8593-1bf9ee665314 is not supported pattern[a-zA-Z_0-9-]{1,128}

Just following up here, I cut a ticket internally to our doc team to get that updated. Thanks for reporting!
