Summary

This generalized script is useful for running tests on bitcoind "to completion" where
the indication of such comes from looking at the logs.

Test Plan
./bitcoind-exit-on-log.sh -h  # shows help message
./bitcoind-exit-on-log.sh --grep "Loading banlist"  # success
LOG_FILE=~/.bitcoin/testnet3/debug.log ./bitcoind-exit-on-log.sh --grep "Loading banlist" --params "-testnet"  # success

mycallback(){ ./bitcoin-cli getbestblockhash; }
export -f mycallback
./bitcoind-exit-on-log.sh --grep "Leaving InitialBlockDownload" --callback mycallback  # success, with best block hash output

Also test IBD on this diff via TeamCity.

Please add braces around the variables everywhere.
What is the use case apart from the IBD script ?

Nit: use braces ${BITCOIND_PARAMS}. $BITCOIND is already a valid variable !

Use -n instead.

What is the use case apart from the IBD script ?

Some examples that I plan to use it for include testing time-to-completion for various features (initial spin-up, reindexing, etc).

Fixes according to feedback.

Rebased + fixed up verbose logging (set -x) on the new script.

If you want my opinion I would have simply set -x from the very beginning of the script (set -euxo pipefail) and only disable it around the sleep loop.
This script is intended to be run by the CI server, so every trace can be useful in case there is a bug in the script, and the detected parameters are no exception. This has a different purpose than an echo statement which is more of a UI for the script.

Oups, you replaced LOG_PID with IBD_PID during the rebase !

Disable verbose logging while printing the help message, otherwise it's impossible to read.
