Fixed loadtest configuration (#84)

Fixed configuring TCP ports.
Removed builder methods from the config, because the defaults were the
cause of a malformed config in the first place.
Moved rpc_addr (renamed to debug_addr) to config, and removed the
default port logic - opening a port which was not predeclared on the gcp
VM spec made the whole container crash.
Added support for disabling the test rpc server if not needed.
Increased disk size for the loadtest CI to fit 3h worth of finalized
blocks.

Simplified CLI api of `tool/src/main.rs`: embedded the secrets into the
config json.

Some kubernetes/docker-related scripts probably need an update.
