jclouds 1.5.2 released

[Adrian Cole]

jclouds 1.5.2 is now released to maven central! This includes all
projects: jclouds core, chef, karaf, and cli

This is largely a bugfix release, and here are the notable updates:

support time-bound signatures for openstack swift implementations
new "name" parameter to ContextBuilder, which allows you to
identify contexts based on used-supplied names.
fixed NPE on aws-ec2 w/vpc security groups
new parameters to set polling interval for node startup commands
Support HP Cloud temporarily signed blobs when using accessKey
authentication

Many thanks to Becca, Andew Gaul, Andrew Bayer, Everett, Ignasi,
Ioannis, and Matt for their work in this release.

We've now begun work on jclouds 1.6, which includes work to reduce the
amount of network calls jclouds uses to perform operations, in efforts
to avoid setting off API throttles. Keep a look out for more!

Cheers,
-Adrian
