Updated SHA256 sum and GPG key id for new GPG key.

As per [AppNeta support](https://support.appneta.com/cloud/content/gpg-key-expiry) on the September 28th 2014 the GPG key for the Traceview APT repository expired. As a result, running this cookbook currently fails as both the SHA256 checksum in the 'remote_file' directive is now incorrect, as is the GPG Key Id.

I have updated the SHA256 checksum from the new key file and verified that I am able to install with the updated checksum and key.

The SHA256 sum and GPG key were fetched in the following manner:

```
[LOCAL] *******@u1410n0:[/var/tmp]$ curl -O https://apt.tracelytics.com/tracelytics-apt-key.pub -s
[LOCAL] *******@u1410n0:[/var/tmp]$ gpg tracelytics-apt-key.pub 
pub  4096R/E04AD2E4 2014-09-29 AppNeta TraceView Package Manager <traceviewsupport@appneta.com>
[LOCAL] *******@u1410n0:[/var/tmp]$ sha256sum tracelytics-apt-key.pub

```

The checksum and key can also be validated via the [AppNeta support](https://support.appneta.com/cloud/content/gpg-key-expiry) article on the key expiration.
