Add WithUpstreamOptions server option

[sevein]

What changed?
I'm adding a new server option WithUpstreamOptions(options ...temporal.ServerOption) enabling users to configure the Temporal server more granularly., e.g.:

opts := []temporalite.ServerOption{
    temporalite.WithNamespaces("default"),
    temporalite.WithDynamicPorts(),
    temporalite.WithPersistenceDisabled(),
    temporalite.WithUpstreamOptions(
        temporal.ForServices([]string{primitives.FrontendService}),
    ),
}
srv, err := temporalite.NewServer(opts...)

Why?
This allows users configuring all server options, like InterruptOn, without the maintenance burden of having dedicated functions.

How did you test it?
Tested locally.

Potential risks
This is a backward incompatible change. Before, temporal.InterruptOn(temporal.InterruptCh()) was used. This pull request proposes to leave the interrupt option undefined to match Temporal's default.

Is hotfix candidate?
