Add parameter base_image and addon_image to BUILD_PLATFORMS

[mauriciopoppe]

Fixes #145

Adds new parameters in BUILD_PLATFORMS referred as base_image and addon_image with the format image:tag

make push-multiarch BUILD_PLATFORMS="linux amd64; windows amd64 .exe nanoserver:2019 servercore:2019;

List of changes:

• made /bin/bash the default shell instead of /bin/sh, I needed to do this to do string addition and indexOf
• updated the cloudbuild docker image to a newer version that has 20.10 and this fix: https://github.com/docker/cli/issues/2722#issuecomment-693395773
• docker build with multiple build platforms with different base images
• created a docker manifest with info about all of these builds including info about the combinations of arch, os and os-version

Output of some snippets used here:

build_platforms=build_platforms="linux amd64; linux ppc64le -ppc64le; linux s390x -s390x; linux arm64 -arm64; windows amd64 .exe nanoserver:1809 servercore:ltsc2019; windows amd64 .exe nanoserver:1909 servercore:1909; windows amd64 .exe nanoserver:2004 servercore:2004; windows amd64 .exe nanoserver:20H2 servercore:20H2"
echo "$build_platforms" | sed -e 's/windows *[^ ]* *.exe *[^ ]* *[^ ]*//g' -e 's/; *;/;/g' -e 's/;[ ]*$//'
linux amd64; linux ppc64le -ppc64le; linux s390x -s390x; linux arm64 -arm64

I used these changes in node-driver-registrar to push all the windows images as well as the manifest:

@pohly I made a small change to the name of the image, from amd64-nanoserver-20H2-windows-canary to amd64-windows-nanoserver-20H2-canary, the lgtm tag was removed because of this

@pohly so sorry I lost your comment, are the images in csi-driver-host-path still failing because of this?

[mauriciopoppe]
