Migrate Logstash plugin

[joshdover]

We need to migrate the Logstash plugin in x-pack/legacy/plugins/logstash to the New Platform.

Subtasks:

• Migrate client-side - this should be prioritized first to help unblock management's migration
  • Refactor all services in public/services to use NP services
  • Move services to plugin class + shim
  • Move logic out of Angular routes & directives into React app
  • Handle dependency between monitoring and logstash (here and here)
  • Migrate to New Platform
    • this could be done as a single step or with a shimming phase. App seems small enough to do in a single step.
• Migrate server-side [NP] Migrate logstash server side code to NP #63135

Things we are not doing:

• Converting everything to TypeScript
  • May make sense to use TS in certain places (eg. plugin class), but we are not converting all the existing code to TS as part of this migration.

Resources:

• Mapping for .logstash index
• Logstash centralized pipeline management docs

Should the Migrate client-side part be prioritized for 7.8?

It is.

@joshdover It might make sense to get rid of angular.js code as well. UI is already implemented in React, so Angular is a glue layer to the platform.
