Users have expressed interest in templating support in feast, to be able to customize things such as dynamodb table names (#2394)

Describe the solution you'd like

We should be able to use a templating engine. Ideally, if added, the implementations should be language agnostic (using something jinja.

Describe alternatives you've considered

An alternative is that any templating should be in a layer above feast. This may be advantageous by keeping feast api surface and implementation simple. At the very least, this decision needs an RFC to determine what the right experience for users should be. This includes what fields are up for templating, when the templating kicks in in the lifecycle of a feast command, etc.
