Move memsharded/hello repository to the conan-io organization

[danimtb]

When using the conan new command, the conanfile.py created points to https://github.com/memsharded/hello and it is a bit weird to use an example out of the organization.

We should move it to a isolated repo in the conan-io org and give it a better name, like: hello-cpp-lib-example

After that, the conan new command should be updated to use the new repo

@memsharded please, give us feedback about this.

I would like to have this done as @jgsogo pointed out in conan-io/docs#1262 (comment)

Do you agree on transferring the repo to the conan-io organization?

[danimtb]

I think having a "conan-hello" repo in conan-community and the binaries uploaded to Conan Center will be helpful for the examples in the documentation too

[memsharded]

Yes, I totally agree.

Probably it deserves a bit of clean-up, because it might have some weird patterns, like the "static_shared" branch, etc. The only problem is the moment I transfer it, it will be broken in develop. I suggest a completely new repo, deprecate mine (older versions of the doc would still use mine!)

[danimtb]

Ok, I will create a new repo with the static_shared contents in the master branch and we will keep your repo too for old references
