Add pluging susbsystem to be able to write custom fetchers/unpackers/signature_checkers

[iilyak]

Overview

The aquaproj has a set of unique features which are not present in other tool managers:

• checksum checker
• custom registry
• automatic extraction of archives
• support for golang tools
• templates in config

Unfortunately there is only a handful of predefined ways to fetch (few github specific methods and plain http). It would be nice to have support for things like:

• JFROG Artifactory
• AWS CodeArtifact
• Azure Artifacts

The aquaproj would benefit from a plugin subsystem which would allow writing plugins. One possible solution could be Extism since it allows:

• isolation of executed code into wasm sandbox
• defining of host functions exposed to plugin
• pattern based allowlist to access filesystem

It can also be used to extend installers to languages beyond golang. There are lots of tools written in rust and zig which compile into single file statically linked executable.

Why is the proposal needed?

I want to be able to extend aquaproj with support for 3rd party tools.
