Command line arguments are only parsed with '='

[solvman]

Command line arguments (some at least) will only work with "=" in the following format:

--public-key=${MINER_KEY}
--node=chainweb-node:1848
--worker=stratum
--thread-count=2
--log-level=info
--no-tls
--stratum-port=1917
--stratum-difficulty=46

Will not work if spaces are used in place of "="
