Title: Add _cat/versions endpoint

If we want to have a full picture of versions running in a cluster, we need to add a `_cat/versions` endpoint.

Response could look like:

```sh
% curl es2:9200/_cat/version?v
node component version
es1 jvm 1.6.0_65-b14
es1 elasticsearch 0.90.10
es1 elasticsearch-mapper-attachment 1.7.0
es1 elasticsearch-lang-js 1.7.0
es1 elasticsearch-analysis-smartcn 1.9.0
es2 jvm 1.6.0_65-b14
es2 elasticsearch 1.0.0.RC1
es2 elasticsearch-mapper-attachment 2.0.0.RC1
es2 elasticsearch-lang-js 2.0.0.RC1
es2 elasticsearch-analysis-smartcn 2.0.0.RC1
```

Closes #4824.

**Note** that this PR requires first #4378 to be merged.
