Fixed nil-reference panic.
fix formatting error in test
Generate CA Certificates that are valid for a bit further back in time.

See bug #1352944. We were generating certificates that were valid 5 minutes ago, to avoid
problems with the clock on the client being out of sync with the clock on the server, but
it seems 5 minutes isn't quite enough to account for real world clock skew. So bump it
up to 1 week.
add some comments about what we are testing.

Also, do the same work for Server and Client certs as well as the CA cert.
Modified test to reflect new default of preferring updates/upgrades.

Introduce environs/bootstrap.BootstrapParams

The user-facing Bootstrap method (i.e. as
used by cmd/juju) will take different parameters
than the provider-specific one (Environ.Bootstrap).
Thus, we introduce a new parameter struct that is
currently identical to environs.BootstrapParams,
but will be changing imminently.
Make environs/bootstrap responsible for tools location

environs/bootstrap now finds available tools, augmenting
or substituting for locally buildable/uploadable tools
as necessary (auto upload) or as specified (--upload-tools).
Environ.Bootstrap is now provided with a list of available
tools, and is not responsible for syncing tools itself.

--upload-series and --series will be obsoleted: we will
upload a single series, and then use that in the metadata
for each supported series.
Explode uploaded tools for each supported series in bootstrap
Fix tests
environs/cloudinit: Wrap tools download inside cloud init in a retry loop
