Build docker images in self-hosted runners to offload dockerhub build

[IsaacYangSLA]

Signed-off-by: Isaac Yang isaacy@nvidia.com

Fixes #1252

Description

The local docker build step (local_docker in deploy) builds the monai:latest from Dockerfile. This PR is to push that image to dockerhub. The build failure seemed related to the load in dockerhub. Moving the build process to our runners can reduce load on dockerhub and the build failure.

The local_docker step takes about 4min20sec~5min, and adding this docker push step does not occupy GPU resources.

** Requiring to add credential (DOCKER_PW of projectmonai) to repo's secrets.
** This PR does docker logout immediately after docker push is done.
