TAK Server 5.0

Updated to support TAK Server 5.0

Uses less memory + Postgres15

Updates postgres to 15 and addresses following issues:

• Cannot connect to database caused by using the public IP for the SQL connection. This worked for some but not all depending on firewall state. It now uses a docker alias of "tak-database" instead of $HOSTIP
• Certificate common name is now the public IP not "takserver". This caused custom python scripts like cotroutesim to require a /etc/hosts entry for takserver to bypass the common name validation error.
• BLUF: You can run TAK Server with 2GB of memory. The memory allocation for takserver was clumsy. It calculated how much memory the box had in total and then carved it up, presumably because this was run on a minimal purpose built VM. Instead we now calculate how much memory is free and then we carve that up, so this still scales. An idle new DB uses < 100MB and the idle TS uses < 1.9GB (on a 4GB i5).
• Fixes #26 since it appears DP + cert handling has evolved again in clients

4.8 REL 31

• Hardcoded docker-compose replaced with variable name
• Works for DO droplets with VLAN
• Check for active ports during setup no longer false flagging ephemeral ports.
• Changelog converted to markdown.
• Improvements to README

The one that works with less than 4GB of memory and 7zip

• 7zip support for Synology NAS
• Big RTFM hard stop for people who do not have a decompressed TAK release
• Increase in PG connection limits to 400 for slower boxes which loop the setup and accumulate stale SQL connections
• Better setup messages
• Automatic CA generation. CA is "LOL" and CN is "takserver"
• No more "Do you want to kill this process as sudo etc". If a port is used - the script stops.

Tested with 4.7 REL 20 on AMD64.

4.7 REL20 with certificate data packages

• Auto generation of user certificates
• Auto generation of certificate data packages for users
• Streamlined setup with removal of a bogus docker stop/start
• Fixed issue with random passwords failing to meet complexity requirement (+15 Alpha-numeric + special char)
• Tested with ATAK 4.7 and iTAK 2.3
