add ./nginx/pac:/usr/share/nginx/pac default share to webserver

[vdelendik]

let's organize default pac share and place sample pac file for proxying setup

[vdelendik]

that's seems to be mcloud or mcloud-agent (mcloud-android) sub-component which knows exactly all details about connected devices... otherwise we have to duplicate knowledge in both places which potentially leads to all kind of mismatch during upgrades etc.

moved to 2.0 to define valid location

[vdelendik]

it might be independent service related to mcloud-agent repo where we provide proxy_port for devices. there is no sense to duplicate the same values on global CE level because number of devices and locations almost uncontrollable.

[vdelendik]

closing as won't fix. pac file usage should be managed by different service aka esg and might be advanced feature of the pro mcloud
