Maintenance: Add pause when building layers

[leandrodamascena]

Why is this needed?

Our layer-building process expects to download the version published on PyPI with the corresponding tag, but it happens that sometimes (probably CDN cache) PyPI takes minutes to point to the latest version and the build fails. So let's add a pause of about 30 seconds in the layer build to give Pypi time to update with the latest version.

ERROR:

Solution

Add a pause of about 30 seconds in the layer build to give Pypi time to update with the latest version.

Acknowledgment

• This request meets Powertools for AWS Lambda (Python) Tenets
• Should this be considered in other Powertools for AWS Lambda languages? i.e. Java, TypeScript, and .NET

Removing the triage label, assigning it to me, and putting it in "On Hold" status until we have the bandwidth to implement this.
