Azerbaijan needs to remain neutral. Since there is no benefit for her. Iran would not attack Saudi, or Azerbaijan either. Iran only has a sea border with Saudi, so it is obviously not possible. Based on my perception from the Turkey, whether we like or not, AKP would lead Turkey for another decade, and AKP is not anti-mullah at all. only when Mursi came into power, and Syria's situation was seemed to fell into hands of MB of Syria, Erdogan got interested in an alliance between Egypt-Turkey-A MB Syria-Qatar. but the fact is that Mursi is gone, seculars are weak in Syria, and Qatar has changed, so Erdogan has started to become closer to mullahs again. Do not forget that he let do laundering for mullahs. Anyway, as long as AKP is in power, IMO, Turkey would not support Azerbaijan in a war. Since they, AKP, do not care about Turkic brotherhood, and they do care for shia-sunni conflicts in some extent.
