Description of PR

Summary: On master Sonic test_show_bgp_summary fails with error KeyError: 'prefixReceivedCount. This happens due to recent update of FRR up to version 7.5, after which key prefixReceivedCount have changed to pfxRcd. So in order to make test pass on Sonic master key should be changed to pfxRcd. This wont affect released Sonic version, because it contains both keys.

@yxieca @wangxin could you please take a look?

[yxieca]

@SavchukRomanLv thanks for address the issue. I noticed that 201911 branch is still not upgraded to FRR 7.5 yet. Do you think you can make the test work for both 201911 and master?

[AndriiLozovyi]

@yxieca Test should work for both master and 201911, below is the output of show bgp summary json on SONiC.201911.220-dirty-20210205.115223 which also contains key pfxRcd
