make Docker build smarter, add Dockerfile.debian (#6344)
this PR makes many changes to the dockerfile in hopes of making it faster to build, download, and upload. 1. Instead of copying the entire repository at once, it first copies the go.mod and go.sum files, then runs go mod download. This allows the dependencies to exist in their own layer, avoiding the need for the build cache there. 2. the compilation of the db-tools is moved to a second image. Since these are not often changed, not needing to rebuild them every time makes things a lot faster for local development. It also reduces the amount that is needed to be uploaded when creating new release - since the db-tools layer will be unchanged 3. each binary is copied individually into its own layer. This allows docker to upload/download each binary in parallel, along with better recovery if the download of the existing 500mb layer fails (since it is done in parts) it also adds a second dockerfile which builds erigon with a debian image, as a start to addressing #6255 while this dockerfile has a greater total image size, the total size of different layers across versions will be smaller, resulting in smaller effective upload & download sizes with all that said - I am not really sure how the existing erigon ci/release process works, so maybe these changes are incompatible with it. # comparison ## docker build speed in both examples, i build erigon, then change a file in core/blockchain.go (resulting in recompilation) these are the produced logs ### CURRENT DOCKERFILE ``` [+] Building 70.1s (18/18) FINISHED => [internal] load build definition from Dockerfile 0.1s => => transferring dockerfile: 38B 0.0s => [internal] load .dockerignore 0.2s => => transferring context: 34B 0.0s => resolve image config for docker.io/docker/dockerfile:1.2 0.4s => CACHED docker-image://docker.io/docker/dockerfile:1.2@sha256:e2a8561e419ab1ba6b2fe6cbdf49fd92b95912df1cf7d313c3e223 0.0s => [internal] load metadata for docker.io/library/alpine:3.16 0.4s => [internal] load metadata for docker.io/library/golang:1.19-alpine3.16 0.4s => [builder 1/5] FROM docker.io/library/golang:1.19-alpine3.16@sha256:4b4f7127b01b372115ed9054abc6de0a0b3fdea224561b35 0.0s => [stage-1 1/5] FROM docker.io/library/alpine:3.16@sha256:b95359c2505145f16c6aa384f9cc74eeff78eb36d308ca4fd902eeeb0a0 0.0s => [internal] load build context 0.1s => => transferring context: 111.58kB 0.0s => CACHED [builder 2/5] RUN apk --no-cache add build-base linux-headers git bash ca-certificates libstdc++ 0.0s => CACHED [builder 3/5] WORKDIR /app 0.0s => [builder 4/5] ADD . . 0.5s => [builder 5/5] RUN --mount=type=cache,target=/root/.cache --mount=type=cache,target=/tmp/go-build --mount=t 61.3s => CACHED [stage-1 2/5] RUN apk add --no-cache ca-certificates curl libstdc++ jq tzdata 0.0s => [stage-1 3/5] COPY --from=builder /app/build/bin/* /usr/local/bin/ 0.2s => [stage-1 4/5] RUN adduser -D -u 1000 -g 1000 erigon 0.8s => [stage-1 5/5] RUN mkdir -p ~/.local/share/erigon 1.0s => exporting to image 2.6s => => exporting layers 2.6s => => writing image sha256:948c68e8d2f64df2c4fa758a370b8de8c4aab65c91c3aeca96662ec8eafb7815 0.0s ``` Since the downloading of dependencies is in the cache - rebuild time does not suffer, but notice that it does not go into its own layer.

Along with this, we can resume after a failure in upload, since we are uploading smaller chunks
