PR description

Eliminates the need to put quotes in a TOML file for the min-gas-price field. this field is now an integer

I think a lower touch solution would be to add an if block for Wei in the TomlConfigFileDefaultProvider -

pantheon/pantheon/src/main/java/tech/pegasys/pantheon/cli/util/TomlConfigFileDefaultProvider.java

Line 59 in 94f39d1

} else { // else will be treated as String

Indeed changing this file is easier and faster. Good comment
