Akamai credentials are automatically detected in the following locations and prioritized in the following order:
1. Section-specific environment variables (where `{SECTION}` is specified using `AKAMAI_EDGERC_SECTION`):
- `AKAMAI_{SECTION}_HOST`
- `AKAMAI_{SECTION}_ACCESS_TOKEN`

2. If `AKAMAI_EDGERC_SECTION` is not defined or is set to `default`, environment variables:

- `AKAMAI_ACCESS_TOKEN`
- `AKAMAI_CLIENT_TOKEN`
- `AKAMAI_CLIENT_SECRET`
3. `.edgerc` file located at `AKAMAI_EDGERC`
