Move `unlockerd` inside `tdexd` and add `UNLOCK_PASSWORD_FILE` config ENV VAR option to make unlocker feature inside `tdexd`

[tiero]

TODO:

• [x] move unlocker functionalities inside tdexd
• [x] add new ENV VAR
• [x] drop old unlockerd binary from cmd and from Dockerfile
• [x] change tdex-box docker-compose and mount the volume with pwd.txt inside according to new ENV VAR
• [x] change documentation in the Dev Portal
• [x] change documentation in the README

To prevent this, should maybe the tdexd "pulls" the password IN instead of being a separated service?

LND does the same apparently, we can have an ENV VAR to specify where the password is.

First thing is to try to replicate the issue with docker compose

1. Create a compose like the following

   
   version: "3.7"

services:

TDEX daemon connected to Blockstream.info explorer

tdexd: container_name: "tdexd" image: ghcr.io/tdex-network/tdexd:latest restart: unless-stopped environment:

• TDEX_LOG_LEVEL=5
• TDEX_NETWORK=testnet
• TDEX_BASE_ASSET=144c654344aa716d6f3abcc1ca90e5641e4e2a7f633bc09fe3baf64585819a49
• TDEX_NATIVE_ASSET=144c654344aa716d6f3abcc1ca90e5641e4e2a7f633bc09fe3baf64585819a49
• TDEX_EXPLORER_ENDPOINT=https://blockstream.info/liquidtestnet/api ports:
• "9945:9945"

• "9000:9000"

  Unlocker with file

  Uncomment to override default command and start tdexd and unlockerd.

  You need to uncomment also the volume down that mount the path used here.

  command: /bin/bash -c "(sleep 1 && unlockerd --password_path=/pwd.txt --interval=10 >& /dev/null &) && /tdexd-linux"

  volumes:

• ./tdexd:/home/user/.tdex-daemon
• ${PWD}/pwd.txt:/pwd.txt

2. Run it with docker-compose up

3. initialize with seed and password and put it in the pwd.txt file in local path

4. check status with docker exec -it tdexd tdex status

5. Restart the Docker engine (or Docker Desktop if on Mac)

Is it unlocker working?

@sekulicd We need to coordinate all documentation and tdex-box reference with new ENV VAR. Refer to first comment in the issue for checklist for completion
