ingest benchmark: after effective_io_concurrency = 100 we can increase compute side parallelism

[Bodobolero]

Problem

ingest benchmark tests project migration to Neon involving steps

• COPY relation data
• create indexes
• create constraints

Previously we used only 4 copy jobs, 4 create index jobs and 7 maintenance workers. After increasing effective_io_concurrency on compute we see that we can sustain more parallelism in the ingest bench

Summary of changes

Increase copy jobs to 8, create index jobs to 8 and maintenance workers to 16
