fix: greptimedb can't work with version >= 0.5

[killme2008]

What's changed?

Close #1754

Fixed GreptimeDbDataStorage can't work with GreptimeDB >= 0.5:

• Rename GrepTimeDbDataStorage to GreptimeDbDataStorage.
• Change queries from deprecated gRPC client to JDBC.
• Upgrade GreptimeDB client version to 0.7.3
• Refactor some code

Test with MySQL monitor:

Not relevant to this PR, but I found that Prometheus Collector is not working, it always adds a prefix _ to app when saving data but not in queries.

I found it is other storage common bug due victoriaMetrics adaptation, we will fix it later.

Btw, may i ask how is the protocol compatibility of greptime's prometheus api? We want to try greptime prometheus api in the future, just like victoriaMetrics as a recommond storage. Because we are designing new data stru and integrating the grafana page capabilities, . thanks.

Sure, GreptimeDB totally supports Prometheus remote storage(and compatible with vmagent) protocols, please read the doc

https://docs.greptime.com/user-guide/write-data/prometheus#a-note-for-victoriametrics-remote-write

And if you want to use PromQL query API, it's supported too
