Feature-90 minute timeout for on-demand capacity mode

We would like to be able to run functions for longer than 15 minutes in on-demand mode. 90 minutes would be parity with the Lambda managed instances mode recently released.

**Description**

see blog post:

https://aws.amazon.com/blogs/compute/announcing-90-minute-function-timeout-on-aws-lambda-managed-instances/

**Additional context**

We still have several jobs that must run on ECS because it is either too costly to rearchitect them for 15 minute time outs or impractical due to the unit of work requiring more time. We would value a single place to run our jobs rather than having some on Lambda and some on ECS. We are much less interested in adding LMI as yet another variant in our platform.

Comienza revisando el timeout solicitado de 90 minutos y la publicación enlazada del blog de AWS Lambda sobre managed-instances; el payload no identifica archivos del repositorio, pruebas ni puntos de entrada de la implementación. Se considera completado definir y proporcionar compatibilidad con capacidad bajo demanda para ejecuciones de funciones de hasta 90 minutos, con un comportamiento que coincida con la paridad solicitada.
