[GRIFFIN-297] Allow support for additional file based data sources
URL: https://github.com/apache/griffin/pull/555
**What changes were proposed in this pull request?**
The PR extends the current support beyond just Avro and Text for various
file based data sources (Parquet, ORC, etc).
- Allows users to specify additional file based data sources like Parquet,
CSV, TSV, ORC etc.
- Above formats are supported in both batch and streaming mode.
- Allows data to be read directly from stand-alone files as well as
directories present in both local/ distributed file systems.
- Allows users to specify schema directly through options (useful for CSV/
TSV types).
A sample config looks like,
```
{
"name": "source",
"baseline": true,
"connectors": [
{
"type": "file",
"version": "1.7",
"config": {
"format": "parquet",
"options": {
"k1": "v1",
"k2": "v2"
},
"paths": [
"/home/chitral/path/to/source/",
"/home/chitral/path/to/test.parquet"
]
}
}
]
}
```
**Does this PR introduce any user-facing change?**
No
**How was this patch tested?**
Griffin test suite. Additional unit test have also been added.

> In the current version of Apache griffin (0.5.0), there is very limited
> support for file based data sources as only Avro and Text files are
> supported.
> I propose the feature to allow support for additional file based data sources
> like Parquet, CSV, TSV, ORC etc in both batch and streaming mode. Since most
> of the above sources already have first class support provided by spark, the
> implementation is straight forward.
> Also, this feature will allow data to be read directly from stand alone files
> as well as directories present in both local and distributed filesystems.
> A sample config would look like,
> {noformat}
> {
> "name": "source",
> "baseline": true,
> "connectors": [
> {
> "type": "file",
> "version": "1.7",
> "config": {
> "format": "parquet",

> "k2": "v2"

> "paths": [
> "/home/chitral/path/to/source/",
