The service install command doesn't take into account the --config-path option

[zah]

To reproduce, run the following command on a fresh installation:

mkdir /tmp/rocketpool
rocketpool --config-path /tmp/rocketpool service install

The result I expected is that the "Rocket Pool package files" (i.e. chains, config.yml, data, docker-compose.yml, settings.yml) will be placed in the designated config directory. Instead, they were placed in ~/.rocketpool.
