self-update

[aricart]

Currently there's no support for self-updating the binary, thus requiring tools like brew etc to provide this functionality.

It's possible but I think there are larger more general problems that we need to fix first - things like where do we place nightly binaries so self update mechanisms can opt into a release or a nightly channel for example.

So I dont want to jump into this we need a strategy that will work for all the tools and more generally provide nightly builds etc.

Alternatively - and perhaps preffered - the install.sh (which this repo dont have) can handle all that so a update is to curl|bash again if thats your thing. This is easier to maintain and easier to fix - a compiled in self updating mechanism that has a bug leaves all those users stranded. A external script with a bug can be fixed for all.

I know this is not exactly self-updating, but managing locally installed versions of nats cli is too darn easy if the Go tooling is installed, which is also easy and convenient to have anyway

$ go install  github.com/nats-io/natscli/nats@main
go: downloading github.com/nats-io/natscli v0.0.33-0.20220513120614-5449781755c0
$ nats --version
v0.0.33-0.20220513120614-5449781755c0
$ go install  github.com/nats-io/natscli/nats@latest
$ nats --version
v0.0.32
$ which nats
~/go/bin/nats
