Add watch support for new pods matching a criteria

[cmosgh]

First of all I just want to thank you for this amazing tool!
I just found it today and it'll definitely stay on my toolbelt.

Any chance there is a way to make it watch for new pods matching the criteria.
In our CD workflow it would be very much in use such a feature

This is something I've wanted to do for a while and I have a (previously local) branch (but I've now pushed it remotely as well to a branch name "pipes") where I'm experimenting with it using named pipes. The problem is that when I use these pipes I cannot get the background kubectl processes to terminate on ctrl+c. I've tried lots of different things to no avail. If you have any experience with this then please help out since I'm out of ideas.

A little up for this issue? Some news about it?
I really ❤️kubtail but I have to restart the command every time a new pod appears, which is frustrating when trying to find an error at startup of a pod

@davinkevin Unfortunately things haven't improved. I'd love to get some help though.

First off, thank you for making kubetail! It's awesome.

I kinda expected a "--watch" feature to be there as in my use case I use kubetail to have a terminal with all logs from a pod in our cluster (super useful for maintenance and monitoring tasks).

So due to CI/CD pushing new versions of my code to the cluster, it causes k8s to kill/spawn new pods and those are not included in the log output - so I have to ctrl-c out of kubetail, wait until the new pods are ready/running and then attach again. That can be a little bit cumbersome.

If I'm too fast, I even get errors that pods are initializing and while kubetail runs it sometimes "overwrites" the terminal UI with error messages in the top-left corner about missing containers.

@bastibense There was actually an awesome pull request that implemented support for this. Unfortunately it broke some existing functionality so I haven't merged it in yet. Would be great if we could get this fixed.

I think "echo hello > /proc/$$/fd/1 &" is a workable solution. See more detail on #67 .
