A few places where names had been hard coded were missed in #2679. This pull request attempts to get the rest of these (although I fear a few more exist).
The hard coding of the logical ids for the role and policy were removed from the json files defining those values.
Additionally, the path and name of the default role and policy were extrapolated as were log group and api gateway names.
The new role path, role name, and policy name values were used to amend the static role and policy.
Commentary in the centralization file was re-added.
Tests were updated
No function or documentation changes occurred by these changes
