Change version to 2.6.0-SNAPSHOT

• bump etcd version to 3.2.7

@aledsage @grkvlt can you please have a look at it? When I import the catalog.bom into my server I can see the following summary which looks wrong as it references some items with version 2.5.0

LGTM

thanks @m4rkmckenna any idea why I'm seeing that issue?

@andreaturli when I tried br catalog add catalog.bom, it worked. I got:

etcd-node:2.6.0-SNAPSHOT
etcd-proxy:2.6.0-SNAPSHOT
etcd-cluster:2.6.0-SNAPSHOT
etcd-cluster-template:2.6.0-SNAPSHOT

What's strange about that catalog.bom is that it adds the library https://oss.sonatype.org/service/local/artifact/maven/redirect?r=snapshots&g=io.brooklyn.etcd&a=brooklyn-etcd&v=2.6.0-SNAPSHOT, and then adds the item from that jar's classpath of etcd/catalog.bom.

If you're testing the PR locally by doing br catalog add catalog.bom, then you won't be getting your changes tested. You'll be using whatever is at mvn sonatype snapshot, which will presumably be the the latest in master. However, I'm surprised that 2.6.0-SNAPSHOT existed in sonatype, given that your PR bumps the version number!

thanks @aledsage I've modified the catalog.bom to use directly the etcd.bom file available in Sonatype

[aledsage]

@andreaturli thanks - the catalog.bom in master has changed so that we don't reference sonatype. Instead it uses the local file (expecting this entire compiled bundle to be added to brooklyn, rather than a standalone .bom file).

I suggest we first merge #22, and then rebase this PR against master and merge it.
