Add ability to look at cube meta during queryRewrite

**Is your feature request related to a problem? Please describe.**
When setting up row-level permissions, I want to make sure that any query on a cube with a tenant id dimension is re-written to filter for that tenant ID

**Describe the solution you'd like**
The queryRewrite function should be passed a parameter that lists out all cubes and allows to inspect the dimensions + measures on those cubes

**Describe alternatives you've considered**
The alternative is maintaining a list of cubes manually. This gets tedious especially when extending cubes.
