Revisit Ctrl-C and Ctrl-D handling in CLI

Analysis

Summary

Exiting when Ctrl-C is typed in all cases seems not the best UX. CLI should align to bash like behavior.

Requirements

Ctrl-C CLI behaviour (similar to bash):

• If auto-connect is enabled (-c option). If prompt occurs for credentials, typing Ctrl-C should exit the CLI process
• As soon as we have reached the CLI prompt,Ctrl-C will NOT exit the CLI whatever the use-case.
• Ctrl-C sent to terminal without any command running print a new line and new prompt.
• Ctrl-C sent to terminal with command running interrupts the running command, print a new line and new prompt.
• Ctrl-D sent to terminal without any text typed-in, the CLI exits.
• Ctrl-D sent to terminal with some text typed-in, does nothing.

Design Notes

Some tests will have to be updated to send Ctrl-D and Ctrl-C when appropriate.
