Migrated localuser.pp to rjil

Earlier localuser def was in a separate module (jiocloud/account).
Since localuser just use types to generate local user account,
It make more sense that to be part of profile rather than a module.
So moving it to rjil::system::account::localuser.

Removed jiocloud/account definition from Puppetfile as it not being
used right now.
Merge pull request #28 from hkumarmk/added_system_account
