shell: logging: Allow users to change SHELL_LOG_BACKEND value

Browse source 
By adding a prompt, users can alter the default value
of SHELL_LOG_BACKEND.
While it makes sense that when you have a shell, the log
messages will, by default, be shown there,
sometimes you want to disable this selection.
For example, when you have a telnet shell (SHELL_BACKEND_TELNET)
and want to debug the network subsys.

When enabled, backend will use the shell for logging.
This option is enabled by default.
Disabling this option disables log output to all shell backends.
Disabling log output to a specific shell backend can be achieved
using the shell backend's LOG_LEVEL option
(e.g. CONFIG_SHELL_TELNET_INIT_LOG_LEVEL_NONE=y).
