Update Dockerfile

[olipayne]

added bottle to the pip installed packages, so we can run ./server.py easily too

You're right, that's a good addition. Should we change the entry point too to be more generic so that we can launch scripts other than the analyzer?

[olipayne]

I guess some people will want to run the docker image with analyze.py and some with server.py, so there's no real right way.

To lower the entry threshold for interested people, you could set up github actions to build a new image on every commit to main branch. I've done something similar here

There's another PR (#19) coming in, which has docker files for server and client. What do you think, should we go with separate files and merge #19?

[olipayne]

Just had a look at #19, it seems to go quite against Dockerfile best practises (non-standard filename, not installing pip packages in 1 line for caching improvements etc.

I think the best would be to expand this PR with a flag you can run during build to define if you want to build for long-running server process, or as a one-off job.
