Subject: [SPARK-17058][BUILD] Add maven snapshots-and-staging profile to
 build/test against staging artifacts

## What changes were proposed in this pull request?

Adds a `snapshots-and-staging profile` so that  RCs of projects like Hadoop and HBase can be used in developer-only build and test runs. There's a comment above the profile telling people not to use this in production.

There's no attempt to do the same for SBT, as Ivy is different.
## How was this patch tested?

Tested by building against the Hadoop 2.7.3 RC 1 JARs

without the profile (and without any local copy of the 2.7.3 artifacts), the build failed

```
mvn install -DskipTests -Pyarn,hadoop-2.7,hive -Dhadoop.version=2.7.3

...

```

With the profile, the build completed

```
mvn install -DskipTests -Pyarn,hadoop-2.7,hive,snapshots-and-staging -Dhadoop.version=2.7.3
```
