[crac] RFR: 8349819: [CRaC] Support FD policy reopen on listening socket

[Radim Vansa]

Adds additional filtering option for `type: SOCKET` in OpenResourcePolicies: `listening: true` which is true for common server sockets. 
With `action: reopen` these implement automatic close on checkpoint and reopening on restore, using the same local address (this obviously won't work well if the restore happens on a machine that does not have the IP used before checkpoint).
