[PATCH v2 0/1] CMD commands improvements

[Svyatoslav Ryhel]

- add ability for 'ums' command to interrupt run of usb
mass storage with any key. This is especially useful on
devices with limited input capabilities like tablets and
smatphones which have only gpio keys in direct access.
Current implementation uses Kconfig entry.

Changelog from V1
- 'continue' command commit was dropped as there already
exists 'pause' command with same function.
- UMS_ABORT_KEYED renamed to CMD_UMS_ABORT_KEYED
