Allow converting AnyConnectOptions to a specific ConnectOptions

This is a decent approach, but in addition I think we could stand to have, e.g.:

impl AnyConnectOptions {
    pub fn as_postgres(&self) -> Option<&PgConnectOptions> { ... }
    pub fn as_postgres_mut(&mut self) -> Option<&mut PgConnectOptions> { ... }
}

etc.

That could end up being a lot of code, of course, though I would personally use a macro to boil that down.

This is also done. This requires a new dependency 'paste' which is a macro crate to create new identifiers from macros.

Yeah, we're fine with paste, it's a decent crate.

Can you merge this and do a release?

@abonander When can you merge this? Is this going to be in 0.6?
