We should avoid tap service call to executor if service URL retrieved from executor is empty.
Added sanity checks to ensure that.

https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.

Passing information of function from router to executor is more efficient than calling the K8S API. This change does that instead of passing only metadata and then executor calling the K8S API again.
Concurrency in the pool manager allows specializing pods concurrently based on a specified limit.

The router taps function service one by one which is inefficient and
increases the burden of executor. This PR aggregates all requests into
one to solve the problem mentioned above.
