--integration-arn doesn't work if the role is on different path

[americanstone]

Description

when pass the integration-arn parameter if the arn has certainn path. the cli fails
e.g.
arn:aws:iam::xxxxxxx:policy/acct-managed/new-relic-lambda-cli

Steps to Reproduce

--integration-arn arn:aws:iam::xxxxxxxx:role/acct-managed/NewRelicInfrastructure-Integrations

I believe this line of code in utils.py

external_id = parse_arn(role_arn)["account"] result["resourcetype"], result["resource"] = elements[5].split("/")

throw error

Expected Behaviour

don't parser the external_id from role arn, allow it pass via cli parameter
