MINOR: sample: Expose SSL captures using new fetchers

To be able to provide JA3 compatible TLS Fingerprints we need to expose
all Client Hello captured data using fetchers. Patch provides new
and modifies existing fetchers to add ability to filter out GREASE values:
- ssl_fc_cipherlist_*
- ssl_fc_ecformats_bin
- ssl_fc_eclist_bin
- ssl_fc_extlist_bin
- ssl_fc_protocol_hello_id
