[dts] [PATCH v2 1/4] framework setting: support configuration file folder change

[Marvin Liu <yong.liu@intel.com>]

By default, configuration files will be loaded from default folder.
It will be inconvenience for backup local configuration files.

In this patch, add one new environment variable "DTS_CFG_FOLDER" which
can change the default folder of configuration files. Execution
configuration file will also be loaded from this folder.
