chore: Optimize dev-chain-fast healthcheck (#241)

There was very long interval for the healthcheck of `dev-chain-fast`.
That's why the startup of `streamr-docker-dev` chain services was
usually very slow. Reduced the interval significantly.

Also improved `--wait` arg to log warnings sooner, and reduced the poll
interval so that we can exit polling sooner.

## Statistics

Before this PR typical chain service startup took about 90s, now it
takes about 24s.

```
streamr-docker-dev wipe
time streamr-docker-dev start dev-chain-fast deploy-network-subgraphs-fastchain --wait
```
