Remove std::move() from local variables with subsequent usage in clearDB()

[Copilot]

Addresses feedback on #143 where std::move() on ClearDB and BootstrapClearDB made subsequent log statements uninformative.

Changes

• Removed std::move() from ClearDB and BootstrapClearDB in set_RFCProperty() calls - short-lived locals don't benefit from move semantics
• Enhanced log statements to include actual key values instead of generic messages
• Aligned pattern with clearDBEnd() function for consistency

// Before
set_RFCProperty(name, std::move(ClearDB), clearValue);
RDK_LOG(RDK_LOG_INFO, LOG_RFCMGR, "[%s][%d] Clearing DB Value\n", __FUNCTION__,__LINE__);

// After  
set_RFCProperty(name, ClearDB, clearValue);
RDK_LOG(RDK_LOG_INFO, LOG_RFCMGR, "[%s][%d] Clearing DB Key Value: %s\n", __FUNCTION__,__LINE__,ClearDB.c_str());

Also added .gitignore for autotools generated files.
