[Feature]: Allow other backends than memory, badger for allInOne mode

[rgaduput]

Requirement

I understand that allInOne is something of a test/poc sort of way of using Jaeger and should not be used in a Production clusters.
But why not to allow other backend type support (like elasticsearch), and let the users decided on their choice of backend ?
Is there any different reasons for this limitation ?

Problem

Unable to use elasticsearch backend for allInOne.

Proposal

Allow to use elasticsearch backend for allInOne.
