Copy remote branch entrypoint to compile and production image stages

[lanxih]

Description

Torchserve docker build with remote branch needs to copy the remote version of entrypoint (dockerd-entrypoint.sh) to the image to keep it consistent with the --branch_name specified for the build.

Fixes #(issue)
We encountered this issue where the torchserve image is expected from --branch_name v0.11.0 in order to work with pinned torchserve pypi package version, but the current entrypoint is out-of-sync and uses additional flag --disable-token from master.

Feature/Issue validation/testing

Re-run bash ./build_image.sh --branch_name v0.11.0 --pythonversion 3.10 --tag test-image to verify that the newly built image now has /usr/local/bin/dockerd-entrypoint.sh from branch v0.11.0 without --disable-token set.

% docker run --rm -it --entrypoint bash test-image
model-server@465e40c1ead4:~$ cat /usr/local/bin/dockerd-entrypoint.sh
#!/bin/bash
set -e

if [[ "$1" = "serve" ]]; then
    shift 1
    torchserve --start --ts-config /home/model-server/config.properties
else
    eval "$@"
fi

# prevent docker exit
tail -f /dev/null

Also ran without branch name to verify the entrypoint has the new flag.

Can you please change this to COPY instead of RUN cp

great question, I also tried COPY but seems that would copy dockerd-entrypoint.sh from the volume (which is the older version prior to cloning from specific branch) to the image, so I suppose that does not work...
