Epic: JetBrains Gateway Integration (IntelliJ IDEA) - beta

[loujaybee]

Context	JetBrains Gateway [1] is the entrypoint for all JetBrains remote development. The scope of this epic is to create a Gitpod JetBrains Gateway plugin and release it to the JetBrains gateway marketplace which allows a user to interact with Gitpod workspaces directly from gateway on their desktop.
Owner	Product - @loujaybee \ Tech - @akosyakov
Value	Enables a user to initiate a Gitpod workspace directly from desktop, without requiring the user to leave their desktop environment and navigate to a browser. Another route for users to discover Gitpod from existing tools they love to use.
Acceptance Criteria	- User can successfully launch and make changes from JetBrains IntelliJ IDEA IDE - User can successfully launch IntelliJ IDEA IDE from Gitpod in the browser - Success metrics are instrumented and working as expected - JetBrains Gateway plugin is released to the marketplace - Documentation for how to install and use the gateway plugin is written and published
Growth Area	Acquisition / Onboarding / Activation & Retention
Persona(s)	JetBrains Users
Hypothesis	- Adding JetBrains desktop support will increase overall Gitpod desktop usage - Onboarding users are less likely to bounce (as users do not have to change their IDE preferences)
Measurement	- Increase in sessions launched from JetBrains gateway to Gitpod
In scope	- Listing, and creating new workspaces directly from desktop (within JetBrains Gateway)
Out of scope	- Launching of workspaces from directly within the IDE - Authentication allowed within JetBrains gateway - Ensuring full support in other IDE's than IntelliJ IDEA
Complexities	- Unknowns with JetBrains Gateway API's - Updating the general Gitpod UX for desktop
Latest Update	21.02.2022 - JetBrains Gateway plugin created and working, currently under functional testing and documentation is still being updated. Primary focus for JetBrains Gateway and Gitpod integration is IntelliJ, other IDE's will follow.
