RDKB-60656 : Available memory check for firmware downloads (#13)

RDKB-60656 : Available memory check for firmware downloads

Reason for change: Before firmware download, we need to check if the
device have enough memory
Test Procedure: 1. while firmware download, available memory check logs
should be seen.
2. If available memory < required memory, firmware download should not
start.
Risks: medium
Priority: P1
