Introduced an Actions interface for plugins in 'action.go' and implemented a corresponding registry in 'registry.go'. Additionally, adjusted rule related behavior in 'Server' to account for actions, with relevant new fields in Ruleset and Rule. This enables multiple actions on a log message based on defined rules and further modularises the codebase, paving the path for addition of more plugin actions.
Introduced a new Connection struct and related functions in `connection.go` to facilitate network connections. Incorporated the `go-parsesyslog` package to parse incoming network data. Implemented functions in `server.go` to accept and handle incoming network connections, bolstering the application's network interaction functionality.
