I maintain my keys only in one place

= I add a key to tuleap =
Add the key to Gerrit

= I add a key to Gerrit! =
Do nothing

= I remove a key from Tuleap =
Remove the key in Gerrit (set-account --delete-ssh-key)

= I remove a key from Gerrit =
Do nothing

= My user is removed from Tuleap =
Do nothing

= My user is removed from Gerrit =
Do nothing

=I migrate a repository to gerrit=
All project members and user group members keys are synchronized with gerrit

----
* I'm a gerrit user if I'm project member or member of user group that have access to a git repository migrated to gerrit
* On Tuleap key management page, I have a link to my gerrit key management if I'm a gerrit user

----
Given I upload 'SSH KEY 1' to gerrit
And I upload 'SSH KEY 1' to tuleap
Then I should not see any error and I should have access to both Tuleap and Gerrit (ideally the key is listed only once in Gerrit)
