Prompt to generate ssh key at import private repo from github

[RomanNikitenko]

What does this PR do?

Change behavior at importing repo from github.

Current behavior:
We try to import repo by ssh regardless if user has ssh key

New behavior:
We check if user has ssh key when user click 'Load repo' button:

Ssh key is available -> we import repo by ssh regardless if repo public or private

Ssh key is not available and repo is public -> we import repo by http

Ssh key is not available and repo is private ->

• We display prompt to generate ssh key
• We generate ssh key and import repo by ssh when user accept this operation
• We remember user's rejection to generate key to don't disturb user anymore and do not display the dialog again when user click on a private repo
• We set http url (not ssh url) in corresponding field when user reject key generation

What issues does this PR fix or reference?
