New string generator for the hash string in NSX resources

[wenyingd]

1. Use chars 0-9,a-z,A-Z to generate the hash string for ID/DisplayName in NSX resources with VPC scenario. It also works on the Security Policy related resources' display name in T1.
2. The length is 6 chars when using the new hash string function.

Test Done:

1. VPC pipeline has passed, the supervisor is running, and the cluster status is ready.
2. T1 pipeline has passed.

Manual Verification

1. Created a subnetset with a long name which is longer than 80 char:

# k get subnetset -n antrea-test
NAME                                                                           ACCESSMODE   IPV4SUBNETSIZE   NETWORKADDRESSES
subnetset-sample-aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa   Private      64               172.26.0.0/26

2. Created a VM using the subnetset to enforce a NSX subnet is created,
3. Check the NSX subnet configurations, and observed its display name is shorter than 80 chars and all chars are allowed.

@wenyingd @lxiaopei I confirmed that we don't change ID for T1, so current change will not affect T1 case.

LGTM, Thanks wenying
