Creating an ahnlich-cli

[deven96]

In order to increase debuggability, we want to introduce a CLI that can be used to query either AI or DB binaries

To do so, we would make use of #18 to aid with parsing into Vec<DBQuery> or Vec<AIQuery>. The requirements are as follows

• Connection to either AI or DB binaries via the Rust client. The server type must be confirmed as well via INFOSERVER
• Makes use of the dsl package to be able to turn raw semicolon delineated strings into queries. It then turns these queries into ServerQuery
• Normal REPL behaviour showing servertype, host and port in the prompt, executing the commands on enter, while showing potential errors that come from dsl parse, db or ai
• Creating pipeline for deploying ahnlich-cli as a binary and also including it within the docker images for ai and db
• Updating README to include CLI description, usage examples and potentially a byzanz-record demo

Nice to have:

• Autocompletion of commands. Rudimentarily this can be simple example usages such as
• History file. Keeping track of all previously issued commands so as to allow the user be able to use arrow key to navigate upwards
• Coloration of reserved keywords
• Clear screen command
