Remove SSH fingerprint confirm with JetBrains IDEs

[iQQBot]

Is your feature request related to a problem? Please describe

During the Jetbrains remote IDE integration, we found that there is an SSH fingerprint confirmation popup that pops up every time a new workspace is opened, and the user can only click on the confirmation for this popup, because the user can’t confirm for himself if the server fingerprint is correct

We want to introduce an API to expose the public key information of the SSH Host so that the plug-in can write to the system in advance, which can avoid this pop-up window and man-in-the-middle attacks

See internal thread

Describe the behaviour you'd like

No need to display this pop-up
