feat(cmd): Create target using address on boundary dev / database init

Creates a target using an address for boundary dev and when first
init-ing boundary (boundary database init).

It also makes this newly created target the default one
(ttcp_1234567890). The target using host sources is now a secondary
target (ttcp_0987654321).
