[27.1 backport] fix: ctx cancellation on login prompt

[thaJeztah]

• backport fix: ctx cancellation on login prompt #5168

- What I did

Implemented a new Prompt function to capture user input called PromptForInput. This function works virtually similar to PromptForConfirmation and handles context cancellation.

- How I did it

Replicate PromptForConfirmation.

- How to verify it
Run docker login and cancel it midway with a SIGINT or SIGTERM or ctrl+c.

docker loginUsername:^C

PromptForInput also allows for hiding user input - for example when the user enters their password.

The original behavior of docker login should still be in-tact with trimming spaces and not showing user input on the password prompt.
