Fix importer workflow timing out

[steven-sheehy]

Description:

• Add a .mvn/jvm.config to configure default JVM build settings
• Add a .mvn/maven.config to configure default Maven build parameters
• Add --threads 1C to support building modules in parallel
• Change artifact concurrency from 5 threads to 10 threads
• Change artifact provider from lightweight to httpclient for better retry configurability
• Change artifact read timeout from 30 min to 10 s
• Change artifact retries from 3 to 5 attempts
• Change build max heap size from 512M to 4096M
• Change connection TTL to 2m to workaround idle connections not closed properly in Azure

Related issue(s):

Notes for reviewer:
Using a parallel build improves ./mvnw verify runtime from 11 minutes to 8 minutes on my machine.

Checklist

• Documented (Code comments, README, etc.)
• Tested (unit, integration, etc.)
