Subject: [PATCH] docker: add support for custom params RPCHOST and RPCCRTPATH

In this commit we add support for two more custom parameters in the
main entrypoint for the `lnd` Docker image script (`start-lnd.sh`)

The two parameters are:
* RPCHOST    to set a custom endpoint for the RPC server
* RPCCRTPATH to set a custom location for the certificate used when
  communicating with the RPC server
