what is the capabilty remoteAppsCacheLimit used for?

Set the maximum number of remote cached apks (default is 10) which are pushed to the device-under-test's local storage. Caching apks remotely speeds up the execution of sequential test cases when using the same set of apks, by avoiding the need to push an apk to the remote file system every time a reinstall is needed. Set this capability to 0 to disable caching.
Eg:-capabilities.setCapability("remoteAppsCacheLimit", 10);
