zdev: add export/import support for site

Browse Source 
Add export and import support for site-specific settings. For each
site-specific configuration, a new site-block will be generated as
below. The same format can be interpreted by the import function and use
the values on the device's site-specific configuration.

Typical example of a site-block in the export file:

[site3 dasd-fba 0.0.f001]
online=1
cmb_enable=0
