controller node reports invalid locale

[Alex Schultz]

After deploying and logging into one of the controller nodes, the following is reported to the user:

_____________________________________________________________________
WARNING! Your environment specifies an invalid locale.
 This can affect your user experience significantly, including the
 ability to manage packages. You may install the locales by running:

   sudo apt-get install language-pack-en
     or
   sudo locale-gen en_US.UTF-8

To see all available language packs, run:
   apt-cache search "^language-pack-[a-z][a-z]$"
To disable this message for all users, run:
   sudo touch /var/lib/cloud/instance/locale-check.skip
_____________________________________________________________________

Additionally attempting to install something may result in a bunch of locale warnings:

perl: warning: Falling back to the standard locale ("C").
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
 LANGUAGE = (unset),
 LC_ALL = (unset),

It appears this warning does eventually go away, not completely sure where it's coming from.

[Maksim Malchuk (mmalchuk)]

this is actually not a bug, this is incorrect configuration of your local and also fuel master node /etc/ssh_config:

$ grep SendEnv /etc/ssh_config
   SendEnv LANG LC_*

this setting will force to set locale after connecting to the remote node.

    Remove ssh_config SendEnv defaults

    Remove from ssh_config all SendEnv parameters. They really don't need and
    mostly causes problems when ssh client used incorrect configuration of
    the system locale settings.

Won't fix for 8.0 since it's a low bug and 8.0 is in SCF.
