Support for adding custom tika configuration

[ahilmathew]

Added support for custom tika configuration to be used in the helm chart via the tikaConfig key in the values.yaml.

This key is optional which when configured will create a configMap and then mounted as tika-config.xml into the running pod.

This is a really nice patch @ahilmathew nice job! One minor suggestion.

Tested locally via k3d. LGTM.
Any thoughts @nddipiazza ?

[lewismc]

@nddipiazza any feedback? Would be great to get this merged if possible. Thanks

[lewismc]

@ahilmathew even if it is commented out by default, I think we should add the tikaConfig element to values.yaml.

@ahilmathew please sync with main branch and also include the default oncfiguration in values.yaml. Thank you

[lewismc]

@t-l-k understood 👍

[ahilmathew]

@lewismc Thanks for the comments. I've updated values.yaml to include the configuration from https://tika.apache.org/2.9.1/configuring.html. Let me know if there is a specific configuration you would like to be included as default.
