Adding Elestio as deployment option

[kaiwalyakoparkar]

Hey there,
I am Kaiwalya, Developer Advocate at Elestio. Elestio has been providing options of fully deploying and managing Imagor application as shown here. I think it would be a great idea if we can add it to official readme/documentation here.
🔔 In addition to this, if you are interested we provide partnership opportunities with tools we support by revenue share upon addition of this method in docs. I see we have an email thread already with all the information, else just shoot me an email at [email protected] :)
