Support of Multiple Function Location Jars

[anoop-awasthi]

We have a use case where Indivisual functions are developed in their seperate Jars due to Isolation reasons and we want to deploy these multiple functions combined in a single deployer.
Single Deployer should maintain child application contexts and loads the corresponding function jar.

Ex-

spring.cloud.function.location=target/upper-1.0.0.jar;target/lower-1.0.0.jar
spring.cloud.function.definition=upperFunction;lowerFunction

We have the same use case. Is there any plan to add this feature?
