Add Event hooks to Plugins

[CEbbinghaus]

Is your feature request related to a problem? Please describe.
There aren't any ways to initialize plugins. Reading Settings and other tasks have to be done in the actions that they are relevant for.

Describe the solution you'd like
Methods to handle LifeCycle hooks of the Plugin such as OnLoad, OnUnload, OnReload...etc, as well as event callbacks of the Application which could include: OnWorkspaceOpen or more granular events: OnDocumentOpen, OnCollectionOpen

Describe alternatives you've considered
Running code when the file is executed is easy and certainly possible but it lacks access to the Insomnia plugin context. e.g no saving to the store to read later or alerting the user to changes in a new version.

Additional context
Related to #2599 which would be another useful hook

Are there specific events you have in mind in the application that you'd like to capture that are not redux actions?

well I specified a few in the description but some I would like to see are

Plugin Events:

• OnLoad (Called after a plugin is loaded. Could be split up into OnLoad (one time) and Initialize (every load))
• OnUnload (Called before a plugin is Unloaded. Useful for plugins to ensure their data is saved)
• OnReload (Called before a plugin is Reloaded. Could be skipped since it would also call OnUnload, but always useful to separate the two)
• OnUpdate (Called after a plugin Updates, e,g to update configs or alert the user to a change Add plugin onPluginUpdate lifecycle event for data / migration management #2599)

Insomnia Events:

• OnWorkspaceOpen (whenever the user opens a document or collection)
  • OnDocumentOpen (more specific event for only documents)
  • OnCollectionOpen (and Collections)
• OnApplicationClose (before the app closes. e.g so any config changes can be written to disk )
• OnWorkspaceUpdate (When a change is pulled via Sync or a workspace file is imported)

Wow great! That's a very very helpful and clear list. cc: @wdawson
