Make interactive mode history persistent

[farshidtz]

The history in the interactive mode isn't preserved across reboots because the file is written at /tmp/chip_tool_history within the snap; which is on tmpfs. For preserving the history, the path can be replaced with a persisted one.

The support for interactive mode was added by #19

This may have been fixed upstream since the history is now being written in the general storage directory which is replaced in the snap. See:

• [Tooling] Configuring default paths by environment variable project-chip/connectedhomeip#30790 (comment)
• Store chip-tool interactive history in the general chip-tool storage directory. project-chip/connectedhomeip#30803

Installed the chip-tool built from Matter SDK version e5f5d67 on ubuntu classic OS:

sudo snap install chip-tool --edge
sudo snap connect chip-tool:avahi-observe
sudo snap connect chip-tool:bluez
sudo snap connect chip-tool:process-control

Enter interactve mode:

$ sudo chip-tool interactive start 
...
>>> pairing onnetwork 110 20202021
>>> onoff toggle 110 1

Check that /tmp/chip_tool_history no long exists, and it is now located inside the chip-tool snap:

$ ls /tmp/chip_tool_history
ls: cannot access '/tmp/chip_tool_history': No such file or directory

$ ls /var/snap/chip-tool/common/mnt/chip_tool_history
/var/snap/chip-tool/common/mnt/chip_tool_history

This issue has been fixed by upstream.

Thanks for testing.
