Ian Wienand 6d23d20f2f linters: add names to blocks
This is preparation for a later version of ansbile-lint, which finds
missing names on blocks.  This seems a reasonable rule, and the
Ansible manual says [1]

  Names for blocks have been available since Ansible 2.3. We recommend
  using names in all tasks, within blocks or elsewhere, for better
  visibility into the tasks being executed when you run the playbook.

This simply adds a name tag for blocks that are missing it.  This
should have no operational change, but allows us to update the linter
in a follow-on change.

Ensure pip is available

This role is intended install the requirements for the pip module on hosts.

Jobs that also wish to call pip via shell commands directly can also use this to ensure pip is available. However, it should be noted that calling pip is ambiguous when supporting many platforms. On some platforms it may install the package under the Python 2 interpreter and in others Python 3. You should use a qualified name (pip2 or pip3) to avoid confusion.

This role will also install wheel components sufficient to run bdist_wheel builds or pip wheel on a source tree.

Role Variables

Output Variables

This variable will be set to a command appropriate for general usage with the pip module virtualenv_command argument on the host. On Python 3 hosts this will be the inbuilt venv module, on Python 2 hosts the virtualenv package will be installed (this is avoided on Python 3 hosts as an unnecessary dependency).
