Various CLI updates

[gadkins]

• Make --update-current-context default to true (i.e. user should set --update-current-context=false)
• Do not require --name / -n option (use positional argument)
• Make --delete-config default to true (i.e. user should set --delete-config=false)
• Handle ctl+c (currently get a stack trace)
• Default to account that corresponds to last created cluster when user runs uffizzi login
• Do not list projects that user does not have access to in UI
• CLI typo “Login successfull” — should be "successful"
• Do not prompt to enter Username when user logs in via email uffizzi login --email jdoe@example.com
