[u-boot-mgr]: Initial u-boot mgr hardening intf
Initial u-boot mgr to harden interface and usage. This
exposes method in D-Bus which other daemon can use to update
U-Boot environment variables, instead of directly using
fw_printenv or fw_setenv tools.
Tested:
Verified able to query the ReadAll, Read and Write
method exposed in this interface.
