Creates the environment directory using alembic.testing utilities, and
additionally creates a revision map and scripts.
Expressed visually, the map looks like this::
A

B
|
C
| \
D D0
| | \
E E0 E1
| / / |
F F1 F2

G G2 G3
| | / |
| | | G4

H--
Note that ``H`` alone has a "depends_on", namely ``G4``.
Uses class scope to create different environments for different backends.
