Add instrumentation to Mojafos for memory,disk use deploy time taken etc

[tdaly61]

It would be really helpful for Mojafos users as wells as Mifos and Mojaloop vNext developers to see

• deploy time taken for major Mojafos components
• total deploy time i.e. how long from ./run.sh until all pods are in running state
• memory used by each major component (Mifos,Mojaloop vNext, PHEE)
• total memory used by Mojafos
• total disk space used by Mojafos

Much of this instrumentation exists in functions in the bash scripts of vNext and can be readily adopted and tailored for use by Mojafos.
