I thought we had already addressed this, but looks like it is not.

@chaitanyaprem what do you think of this proposal?
In status-go we should have to implement a

type OnlineChecker interface {
	IsOnline() bool
}

and use the option WithOnlineChecker(myOnlineChecker) when setting up the node.

[richard-ramos]

I do see however that in status-go, being online in the FilterManager has a different handling initially, so I'll add a function to be able to override the onlineChecker for filter.
