This commit adds postgres_fdw.application_name GUC which specifies a value for application_name configuration parameter used when postgres_fdw establishes a connection to a foreign server. This GUC setting always overrides application_name option of the foreign server object. This GUC is useful when we want to specify our own application_name per remote connection. Previously application_name of a remote connection could be set basically only via options of a server object. But which meant that every session connecting to the same foreign server basically should use the same application_name. Also if we want to change the setting, we had to execute "ALTER SERVER ... OPTIONS ..." command. It was inconvenient.
