Introduce proof of concept for binman's new option which provides sign
and replace FIT containers in binary images.
Usage as example:

binman replace -i flash.bin -f fit.fit fit
to:
binman sign -i flash.bin -k privatekey -a sha256,rsa4096 -f fit.fit fit
and to this one if it's need to be extracted, signed with key and put it
back in image:
