CLI persistent configuration

The CLI should store persistent configuration in an OS-specific location:

Linux/Unix:

~/.config/infinispan

OS X:

~/Library/Java/infinispan

Windows:

$APPDATA/Sun/Java/infinispan

This location should contain:

cli.properties
aliases
history

The configuration properties should be exposed through a config command.

Supported properties:

autoconnect-url::
Specifies the URL to which the CLI will automatically connect to on startup. Example:
*config set autoconnect-url http://user:password:11222*

autoexec::
Specifies the path of a CLI batch file to execute on startup. Example:
config set autoexec /home/user/my-cli-batch-file

trustall::
Specifies whether to trust all server certificates without supplying a trust store. Example:
config set trustall true

truststore::
Specifies the path of a truststore to use to validate server certificates. Example:
config set truststore /home/user/my-trust-store.jks

truststore-password::
Specifies the password of the truststore to use to validate server certificates. Example:
config set truststore secret
