[ArmBase] Modified function name.

setInitialTrrigerStaus -> setInitialTrrigerStatus
setServerConnectStaus -> setServerConnectStatus
[ArmBase] Modified argument name.

use the "available" of variable name in the sense that "Connection is available".
true : Connection is available.
false : Connection is not available.
[ArmBase] Modified the function argument. (deleted unnecessary argument)

the function's argument "type", represents the details of the "available."
Therefore, I can determine the state in "type"(even if there is no "available").
