The meta-openembedded/meta-installer/meta-anaconda,
there are too many meta-*, with a simple search in OE,
it seems breaking the traditional naming.

How about still name the top level 'meta-insatller', and
change the name of enable setting.

- For the target build, enable it by DISTRO_FEATURES_append = " 
anaconda-support"

- For the host build, enable it by DISTRO = 'anaconda'

Without above setting, the anaconda installer does not work even
though meta-installer included. Which other installer could put
here and work with their ways.

- Rename the existed README -> README.anaconda, and create a
   new one to introduce meta-installer as an installer framework.

- Rename the installation image core-image-installer to core-image-anaconda

One side effect is we have to keep LAYERDEPENDS_meta-installer
with a maximal set (which means for other installer, it may not require
these depends layers), but I think it is acceptable. Other meta-* layer
may have the same issue.
