Update default config in EC2 construct for Restate 1.3.0

[pcholakov]

This change updates the default baseline restate-server config deployed by the EC2 construct to the following:

roles = [
    "worker",
    "admin",
    "metadata-server",
    "log-server",
]
node-name = "restate-0"
cluster-name = "Restate"
default-num-partitions = 4
rocksdb-total-memory-size = "512 MB"

[admin]
bind-address = "0.0.0.0:9070"

[admin.query-engine]
memory-size = "256.0 MiB"

[ingress]
bind-address = "0.0.0.0:8080"

This fixes #72

Thanks for updating the cdk construct @pcholakov. Is it possible to not set the roles explicitly? Otherwise, we will have a bit of trouble when splitting the http ingress from the worker role.

[tillrohrmann]

Can we not set the roles explicitly? Otherwise it's gonna be problematic once we enable the http-ingress role by default because then this deployment won't run the ingress once we release 1.4.0.

That's a reasonable thing to do! I'll update for the release.
