Code review comment for lp:~thumper/juju-core/fix-local-bootstrap-json

Reviewers: mp+187955_code.launchpad.net,

Message:
Please take a look.

Description:
Fix local provider bootstrap.

The environment configuration was being serialized
through JSON, which was coercing the integer values
to float64.

The validation schema checks were strictly looking for
integers. This has now been changed to ForceInt.

Test added.
