[PATCH v4 1/4] fsmonitor: add two new config options, allowRemote and socketDir

["Eric DeCosta via GitGitGadget" <gitgitgadget@xxxxxxxxx>]

From: Eric DeCosta <edecosta@xxxxxxxxxxxxx>

Introduce two new configuration options

   fsmonitor.allowRemote - setting this to true overrides fsmonitor's
   default behavior of erroring out when enountering network file
   systems. Additionly, when true, the Unix domain socket (UDS) file
   used for IPC is located in $HOME rather than in the .git directory.

   fsmonitor.socketDir - allows for the UDS file to be located
   anywhere the user chooses rather $HOME.
