Issue Description

Type: feature request

Describe what happened (or what feature you want)

Since 1.7.0, Sentinel has supported configuration via the properties file (except the project.name property). The project.name property is not supported due to the legacy logic (compatible with the legacy default path ~/logs/csp/${appName}.properties), which is rarely used. So we may deprecate the legacy logic in the next few versions and then support configuring project.name via the properties file.

Further discussions are welcomed!
