Virtual hosts for data collection (#14464)

* support multiple hosts at pluginsd structures

* cleanup obsolete code

* use a lookup hashtable to quickly find the keyword to execute, without traversing the whole linked list of keywords

* more cleanup

* move new hash function to inlined.h

* minimize comparisons, eliminate a pre-parsing of the first keyword for each line

* cleanup parser from old code

* move parser into libnetdata

* unique entries in parser keywords hashtable

* move all hashing functions to inlined.h, name their sources, simple_hash() now defaults to FNV1a, it was FNV1

* small_hash() for parser

* plugins.d now can switch hosts, and also create/update them

* update hash function and hashtable size

* updated message

* unittest all hashing functions

* reset the chart when setting a new host

* remove host tags

* enable archived hosts when a collector pushes host info

* do not need localhost to swtich to localhost

* disable ARAL and OWA with -DFSANITIZE_ADDRESS=1
