* fix: default the write cli command to the http default port.
The all-in-one write api is based on influxdb cloud's v2 http api, which
uses the 8080 http default port. This changeset will
allow 'influxdb_iox write' to work against default influxdb_iox
all-in-one without needing to use the --host option to change the port.
It should not change behavior for existing users of `--host`. It adds a
new configuartion option call `--http-host` to set the http port
separately from the gRPC one.
