acquisition/victorialogs: add new datasource

[zekker6]

Related issue: #3307

Data source supports:

• cat mode with automatic adjustment of poll interval (same as one at Loki datasource)
• tail mode by using tailing API

Most of the logic is exactly the same as Loki datasource.
The only difference is related to adding support of live dailing and different response formats.
VictoriaLogs uses newline delimeted JSON for both reqular query and tail modes.

Tested locally with the following config:

source: victorialogs
log_level: debug
url: https://vlogs-endpoint
mode: tail
limit: 1000
query: |
  app_name:nginx
labels:
  type: nginx

this should be listed in the Makefile too -- the only reason to "register" datasources is to optionally exclude from the builds with a tag, and still list them in "cscsli version"

Added this to Makefile in f4603e1, thanks for noticing
