This includes:

* an eBPF object built with a newer kernel (4.14)
* an increased threshold for guessing offsets, which is necessary for
the eBPF tracer to work on Google's Container-Optimized OS (used by
GKE)

Release 1.7.1

Update install instructions to use weave namespace

Remove default values from URL state hash

Correctly handle Time Travel resuming in Monitor

* client: Fix uptime sort in table view

Duration dataType for table columns is now sorted as numeric value.
Default sorting is kept as ascending and text is left-aligned, unlike
numbers.

* Make non-second unit show up in tests

Check if k8s resources are supported in `runReflectorUntil`

Change pausedAt format from moment() back to ISO string

`isResourceSupported` checks whether a kubernetes resource is supported by the api server.
This ensures that, if the probe is unable to communicate with the api server, the call is retried until a true/false response.

If `isResourceSupported` returns false, `ListAndWatch` is not called and `runReflectorUntil` just exits.

logReadCloser: ensure EOF after `Close()`

Adding the !EOF check to the loop condition ensures not reading from closed channels.

This change makes the underlying reader set their corresponding `eof` slot to true on termination.
This make the overall logReadCloser converge to EOF in case of errors of the underlying readers, therefore prevent spinning on read.

`bufio.Reader.ReadBytes` may not return io.EOF when `Close()` closes the underlying reader.
For instance, closing logReadCloser from the Scope App makes `bufio.Reader.ReadBytes` produce the following error: `http2: response body closed`.

Release 1.7.0

Stop page router on App unmount

Set a timeout to Terminal animation

If the animation has no effect, `onTransitionEnd`'s handler is not be called.
Since `onTransitionEnd`'s handler controls whether the terminal is shown or not (by passing `connect=true` as a Terminal prop), set the `animated` variable to true after a timeout.

Stop fetching ReplicaSets and ReplicationControllers

The function now only takes Deployments into account.

Bump ui-components to v0.4.18

refactor: extract common code in endpoint mapping

Reading pod logs returns all container logs

'updateKubeFilters` returns early if there are no namespaces

Replace them with sync.WaitGroup.

This change makes sure an empty `APITopologyOptionGroup` struct is not created for namespaces, if there are no namespaces to report.

This isn't quite as neat as we'd want to make it, because two of the
three call sites still require a closure, but it's still an
improvement.

Note that every instance of MapEndpoints only ever maps to one
topology, which, furthermore, is a core report topology. Hence we can
just parameterise MapEndpoints with that topology, and then the map
functions can return just the node ids.
