docker vitess/vtctlclient: Install curl#7466
Conversation
Install curl into the docker image vitess/vtctlclient. That way,
for clients using this container, not only can they interact
with vtctld via vtctlclient, but they can also interact with
vtctld and other Vitess components via their HTTP APIs, and can
also interact with the Kubernetes API server over HTTP.
When tested with Docker Desktop for Mac, Docker version 20.10.2,
using the command
docker build --compress -f Dockerfile -t "vitess/vtctlclient:latest" .
the original Dockerfile generates an artifact that is 94.4MB
(according to docker image ls), whereas the new Dockerfile
generates a 102MB image, about an 8% increase in the image's
size.

Just adding a note here: before this merged, https://hub.docker.com/r/vitess/vtctlclient/tags?page=1&ordering=last_updated&name=latest showed Compressed Size as 36.24 MB. I'll write what the size is after the new latest image is built and pushed. |

I would understand if the team would rather not include this dependency in this slim image.
