Updating changelog for new release v0.5.5

Dyn: cache records per zone using zone's serial number

exoscale: bump version to 0.11

Set Linode user agent

Configure req timeout calling k8s APIs

Signed-off-by: Yoan Blanc <yoan.blanc@exoscale.ch>

When running in a pod sometimes the request to get ingreses/services
stalls indefinitely. A simple pod restart fixes this. Hard to reproduce
but I got lucky and did thread dump which revealed a gorouting blocked
on call to k8s.

What's new is a `--request-timeout` flag that makes requests to k8s
bounded in time. The default is 30s - this may cause some deployments
with a slow api-server to timeout.

Linode Provider Implementation

The only thing preventing use of a smaller interval is the API request
limit. Caching records by the zone's serial number would let users set a
smaller interval and still not hit Dyn's request limit if there aren't
any changes to the zone since the last time external-dns has run.

In a dynamic setting bigger interval is still the main throttling
mechanism.
