docs: namespaces: convert to ReST

Rename the namespaces documentation files to ReST, add an
index for them and adjust in order to produce a nice html
output via the Sphinx build system.

There are two upper case file names. Rename them to
lower case, as we're working to avoid upper case file
names at Documentation.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

-There are a lot of kinds of objects in the kernel that don't have
-individual limits or that have limits that are ineffective when a set
-of processes is allowed to switch user ids.  With user namespaces
-enabled in a kernel for people who don't trust their users or their
-users programs to play nice this problems becomes more acute.
-
-Therefore it is recommended that memory control groups be enabled in
-kernels that enable user namespaces, and it is further recommended
-that userspace configure memory control groups to limit how much
-memory user's they don't trust to play nice can use.
-
-Memory control groups can be configured by installing the libcgroup
-package present on most distros editing /etc/cgrules.conf,
-/etc/cgconfig.conf and setting up libpam-cgroup.
