[Infra UI] Allow for passing arbitrary KQL expressions in the entry urls

[weltenwort]

By introducing a parameter (e.g. ?filter=...) that allows passing arbitrary KQL expressions in the link-to entry routes (see #23246), other parts of the UI can pre-populate the filter with expressions that the infra ui can not interpret. Examples for that would be APM filtering by a transaction id or an ip address.

The KQL expression should be combined using a conjunction with the other filters derived from the parameters (such as the hostname or container id filter). The route /link-to/host-logs/host1?filter=transaction.id:123 would result in the KQL expression (${CONFIGURED_HOSTNAME_FIELD}:host1) and (transaction.id:123) being used as the initial filter.
