Relocate hazelcast-remote-controller [DI-639] (#1556)

In hazelcast/hazelcast-remote-controller#75,
`hazelcast-remote-controller` is deployed to a different repository to
address build issues. Update the paths to suit.

Also:
- updated Maven central URL as per
hazelcast/hazelcast-mono#4897
- updated Maven central URL to use `HTTPS`, as `HTTP` is [no longer
supported](https://maven.apache.org/docs/3.8.1/release-notes.html).

Fixes: [DI-639](https://hazelcast.atlassian.net/browse/DI-639)
