DOCKER_HOST not taken into account

[socotra69]

What happened:

• In a context where the docker host is different from the default configuration, the docker services cannot works.
  In other word, the DOCKER_HOST env var is not used by the program.
• in my case in did not work in a docker dind context setted up on a bitbucket pipeline

What you expected to happen:
DOCKER_HOST env var should be the law.

How to reproduce it (as minimally and precisely as possible):
Create a docker service and expose it from another host.
Set the DOCKER_HOST var on the machine.
Validate conf with a simple docker run busybox.
Start horusec

Anything else we need to know?:
It is related to the docker client creation.

horusec/internal/services/docker/client/docker_config.go

Line 25 in 02a5f25

dockerClient, err := docker.NewClientWithOpts(docker.WithAPIVersionNegotiation())

it should be :
dockerClient, err := docker.NewClientWithOpts(docker.FromEnv)

Environment:

• Horusec version (use horusec version): latest
• Operating System: linux / docker dind
• Network plugin / Tool and version (if this is a network-related / tool bug):
• Others:

Hello @socotra69

Sorry for the delay in returning and we really appreciate the feedback.
This is a very interesting idea, the engineering team will check as soon as possible to inform you about this change and its impacts on Horusec-CLI

If the impact on the tool is low, it is a very valid exchange, otherwise we will have to assess how we can make the appropriate change without impacting user interaction.
