environs, juju: require admin-secret

The admin-secret configuration value is required
for bootstrapping and connecting to an environment,
but we can't make config.Config require it because
it should never be pushed into the state.

So we add checks to juju.NewConn and implementations
of Environ.Bootstrap to require that it be set.
This unfortunately means that all tests must
connect with authentication set, which means
the changes are necessarily bulky.

environs/ec2: tear down suite properly

LiveTests wasn't destroying the environment.

Also simplify ec2.Destroy a little, now that the AllInstances
method exists.

environs: added global open/close/ports

Added the definition of OpenPorts(), ClosePorts() and Ports()
to Environ and changed the implementations of dummy and ec2.
dummy only supports instance firewall mode, ec2 both. The
common test for the global mode is skipped if the environment
does not support that mode.

environs: ec2 and dummy default to instance

The validation of the configuration for the providers
ec2 and dummy now exchanges "default" with "instance".
The implementations of the global mode has been rolled
back to avoid failing tests. A later change will
prohibit opening and closing of ports on instances
in the global mode.
