Subject: [PATCH] Use env var IPA_CONFDIR to get confdir for cli contexts

For 'cli' and 'cli_installer' contexts, the environment variable
IPA_CONFDIR overrides the default confdir path. The value of the
environment variable must be an absolute path to an existing
directory. The new variable makes it much simpler to use the 'ipa'
command and ipalib with a local configuration directory.

Server and server installer contexts do not use the env var.
