fix(reana-admin): respect service domain when cleaning sessions (#687)

Removes hard-coded infrastructure component host name domain
"svc.local.cluster" during interactive session clean-up procedures,
since this assumption is not really necessary and would not work under
some deployment scenarios, such as on SSL-RIVER.

Closes reanahub/reana#457
