Additional Args and configurable docker image source (RDT-971)

[timoxd7]

Configurable Docker image source

Added esp_idf_root to be used as source for the docker image. Can be used to select docker images hosted on different accounts or servers.

Additional arguments

Added additional_args to add custom arguments to the docker run command. Can be used to enable ccache usage, only add ccache ci action and add the following lines:

-v ./.ccache:/root/.ccache -e CCACHE_DIR=/root/.ccache

Only make sure the .ccache folder is created if no cache was already build (always on the first run).

@timoxd7 thank you for the contribution, it looks good to me.

I would only suggest a bit more precise names for the parameters you introduced.

And could you please describe them in the README.md too?

[key]

It would be good if the image source could be switched.
@timoxd7 does not watch this PR?

[timoxd7]

@key Sorry, forgot about it. Will check right now!

@kumekay I just changed the names and added a documentation to the README.md file
