tls Dockerfile: Move from alpine base

[surajssd]

Description

This commit changes the deploy/tls Dockerfile to move from alpine
based image to a fedora based image because The cfssl package was
removed from the alpine package repositories

Why is this needed

Currently one cannot build image due to unavailability of the package.

Checklist:

I have:

• updated the documentation and/or roadmap (if required)
• added unit or e2e tests
• provided instructions on how to upgrade

IIUC the package has not been removed, but disabled: https://gitlab.alpinelinux.org/alpine/aports/-/commit/87380093c842e135ad4babaaca855f7abb2822cd

You could also build the package as part of Docker image building for less intrusive alternative:

FROM alpine:3.11 as cfssl

RUN apk add alpine-sdk gnupg git
RUN addgroup adm abuild

COPY --chown=adm:adm APKBUILD /usr/src/cfssl/

WORKDIR /usr/src/cfssl/

RUN mkdir /var/adm/ && chown adm: /var/adm
USER adm

RUN abuild-keygen -a -i
RUN abuild -r

FROM alpine:3.11

COPY --from=cfssl /var/adm/packages/src/x86_64/cfssl-1.5.0-r1.apk ./
RUN apk add --allow-untrusted ./cfssl-1.5.0-r1.apk

Hey @surajssd, #90 just landed and has changed the sandbox significantly. Would you mind having a look at the changes and confirm if this change is still something you'd like to see?

The packages has been re-enabled, so I guess this is no longer needed: https://gitlab.alpinelinux.org/alpine/aports/-/commit/91367d5d1c5664351d1391f2c28acdab23c92268.

Thanks, I will close this out!
