Moving `deletePipe()` in `componentWillUnmount()` ensures the pipe is deleted when:
1. the terminal is closed
2. the terminal is closed when closing the pod panel

The pipe still does not get deleted when popping out the terminal.

Fetch cronjobs from 'batch/v1beta1'

This applies if kubernetes' version is >= 1.8.
Otherwise fetch cronjobs from 'batch/v2alpha1'.

Upgraded from 99c19923, branch release-3.0.

This required fetching or upgrading the following:
* k8s.io/api to kubernetes-1.9.1
* k8s.io/apimachinery to kubernetes-1.9.1
* github.com/juju/ratelimit to 1.0.1
* github.com/spf13/pflag to 4c012f6d

Also, update Scope's imports/function calls to be compatible with the new client.

vendor: bump tcptracer-bpf

Fixes #2796

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.
