More configuration flexibility in InputDataPolicy

Some additional flexibility will be good to add.

1. Choose InputDataResolution policy according to `jobType` specified in CS.
-> Lets say i want only `User` job to use `InputDataByProtocol` and other job to use `DownloadInputData`

2. If there is no locol protcol that we want to use for streaming fallback to download policy.
-> Curently for streaming p[rotocols we can specify Local and Remote protocols as:
```
# List of protocols to use for streaming
Protocols
{
# This list is used if the we are getting a file from a
# StorageElement local to the site we are running on
Local = file, xroot, root
# This list is used if the SE is not local
Remote = xroot, root
}
```
Lets say if the `Remote` part is empty and no local protocol available, then use the default policy.(i.e. `DownloadInputData`)
