The `client` variable was colliding with the `client` import in various
files. While it didn't conflict in all files, there was inconsistency
in the naming, sometimes using the confusing `cli` name (it's not the
"cli"), and such names can easily start spreading (through copy/paste,
or "code by example").
Let's make a one-time pass through all of them in this package to use
the same name.

Now client have the possibility to set the console size of the executed
process immediately at the creation. This makes a difference for example
when executing commands that output some kind of text user interface
which is bounded by the console dimensions.
