Feat: anvil -d, anvil restart, anvil exit, anvil status (container fixes)

[sambacha]

Component

Anvil

Describe the feature you would like

Anvil graceful handling of exiting in different running environments

Anvil process management & container improvements

anvil -d would send anvil to the background process, additionally a flag of --log would redirect the application logs to standard streams, i.e:

# implies chmod -R g+rwX /var/log
/dev/stdout /var/log/anvil.log

Note: these commands would be sent from a separate shell environment (but same user)

anvil restart : exit gracefully and start anvil again (using SIGINT)¹
anvil exit : exit gracefully (using SIGINT)

now with anvil -d being used and the command anvil exit you would use SIGTERM²
