all: add prefix "awwan." to the name of temporary directory

Each time the new session is created in local or remote, it will
create new temporary directory.
Previously, the name of temporary directory is random 16 characters
and numbers.
To distinguish this directory with others, we add prefix "awwan." to
the name.
